These principles are intended for management in the development of procedures ~;nd instructions as we11 as for the solutio~. to pro- cedural and organizational questions concerning the rates of con- sumption or fuel and power resources and the production and opera- tiona~ needs of industry, conat~uctior., transport and rural and - municipal economies at all levels of planning. These basic princ~ples ar.e being introduced in place of the Basic Principles for Fi~:ing Rates of Consumption of Fue1 and Thermal and Electric Power in Industry, approv~d by the USSR State Plan- ning Committee, 1 April 1966. The basic principles were prepared by USSR State Planning Commit- tpe experts N, A. Vasin,.E. I. Vertel', G. A. Lobanov, B. V. Mikhaylov, A. M. Nekrasov, G. M. Pokarayev, A. Kh. Sal~'nikov, P. V.

The e8tablishment of rates.of consumption for fuel and thermal and electric power is accomplished at all lpvels of planning and economic activity in accordance - ~ with the Syatematic Instructions for the Formation of State Plana for the Economic and Social Development of the USSR, the current Basic Principles and the apecialized procedures and instructions that correspond to these documents. All expenditures of fuel and thermal and electric power on prig?ary and secondary - indust-ial and operational needs (heating, ventilation, ligl~ting, water s?~;:ply, etc.) r are sub~ect to rate fixing, includircg network. losses, rega~dless of th~. extent of the demand for the resources indicated or the sources of the power. . 1.4. Fixed rates of consumption for fuel and thermal and e?ectric power are planned indicatora of the expenditure of these resources per unit of production (or work) of a specified quality. 1.5. The fixed rates of consumption of fuel and power re~ources are formulated sep- arately for furnace fuel oil at a nominal rate, for diesel fuell and for thermal and electric power. In addition to the f ixed rates of consump~ion f or fuel and thermal and electric power, f ixed rates of consumption for compressed air, oxygen and water for the production of goods and services are also established in enter- priaes. _ Generalized unit energy expenditures.(desigu, plan Rnd sctual) are determined for - the overall appraisal of the effectiveneas of utilization of fue~ and power re- _ sourcea in the production of aingle-type or interchangeable goods (or work). These - include the expenditure of all types of fuel and power in the production of goods ' and services, converted in~o units of conveiztionai iuel. In this case, the unit energy expenditures are determined on the basis of the correaponding unit expendi- turea of fuel and thermal and electric power for the production of goods and ser- � vices and the standard fu~l equivalents of thermal and electric power. 1.6. Fixed rates of consumption of fuel and thezmal and electric power are used to _ plan the expenc'iture of these resources and their efficiency of ~tilization. The - implementation of the established rates is a necessary condition for ~conomic stimu- ' lation t~ conserve fuel and power resources. _ 1.7. Fix~ed rates of c~~nsumption for fuel and thermal and electric power must: -be developed at all levels of planning on a aingle systematic basis for the entire range of products and types of services in accordance with the sort of organization ~ cited above; -take into consideration the manufacturing conditions, the achievements of scientif- ic and technical progress and the plans aasociated with oraanizational and technical = measures which provide for the efficient and effective utilization of fuel and ther- mal and electric power; _ In theae Basic Principles the general term "fuel" is used for both furnace fuel - - oil and diesel fuel. _ r 2 - FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 ' FOR OFFICIAL iTSE ONLY - be systematically reviewed witb consideration being given to the,planned develop- - ment and technical progress of msnufacturing an~ to the most ePf icient indicators - for the utilization of fuel and power resources that are obCained; - contribute to the maximum mobilization of internal re~ources, to the conservatiarl _ of fuel and thertnal and electric power, to the ac~omplishment of planned tasks and to the achievement of good economic results in production. 2. Classification of the Fixed Rates of Consumption . 2.1. The fixed rates of consumption of fuel and thermaS and electric power in manu- facturing are classified according to the following basic criteria: - according to ~he degree of aggregation--individual or group; - according to the camposition of the expenditures--production or general indus- trial; - according to the operational period--yearly or quarterly (monthly rates may also _ be established at enterprises). 2.2. The individual fixed rate of consumption is that rate of consumption of fuel . , and thermal and electric power for the production of a single item (or work), estab- liahed according to types of fuel and power consuming units, installations, machinea _ (steam and boiler, furnace, vehicle, aircraft, etc.) and the production layout as- _ sociated with specific conditions in the production of goods (or work). The ratea may also pertain to individual units, installation~, machines and product~.on lay- outs. - 2.3. The group rate is that f ixed rate of cansumption of fuel and thermal a:~d elec- ~ tr3c power for t~;a production of a planned vclume of univariate goods (or work) in accordance with the established product list at different planning levels-- national economy, ministry (or d~partment), union republic, association and. enter- - priae. 2.4. T'he Froduction rate is that fixed rate of consumption of fuel and thermal and el.ectric power which takes into account the expenditure of these resourcea on pri- ~nary and secondary groduction processes in the productjon of a given type of goods _ (or work), the expenditure on maintenance of production machinery in the hot re- serve, on heating up this equipment and restarting it after scheduled maintenance and cold downt~me, and on the technically unavoidable energy losses during the operation of ihis equipment. , In planiling rates of fuel consumption, only the production rates of consumption for the production of goods (or work) are established. ~ 2.5. The general industrial rate is that planned rate of coneumption of fuel and - - thermal and electric power which takes into account the expenditure of power on the primary and secc~ndary production processes and the secondary need~ of industry (the - _ general industrial, shop and plart requirements for heating, ventilation, lighting, - etc.) as well as the expend:,cure for technically unavoidable energy losses in trans- formers and thermal and electric networks of enterprises (shops) during the produc- tion of given goods (or work). 3 - FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 I FOR OFFICIAL USE ONLY 3. Compositior? of Figed Rates of Consumptiion _ 3."t. The composition of the fixed rates of consumption for fuel and thermal and electric power is a list of items of expenditure which are taken into accouat in the fixed rates for the production of goods (or work). This list is determined in accordance with special procedures and regulations whic:h have been developed with re~ard to particular characterisCics in the produc~tion ot the goods (or work). On - rhe basis of these special procedures amd regulations, the specific e.ompoaition of the fi.xed rates of consumption is determined at each enterprise. _ A mod~l camposition of fixed rates of consumption for fuel and thez~s.al and electric - power for industrial enterprisea is attached. _ 3.2. At enter~rises manufacturing similar or diversp products according to vari~us produ~tion layouts or on diff~rent types of equipm~nt, it is expedient when calcu- - lating the fixed rates of consumption to allocate the general industrial shop and - planr. expenditures of fuel and thermal and electric power for the producLion of ' goods and work in a manner that is proportional to the consumption of power 3n the prodL~c~.ion pr~cesses or in a manner that depends upon the extent of~services Ab- z.ai.:aed fro:~ the auxiliary or subsid~ary shops, namely: _ _ a} far tranaportation sr?ups--pr~portional to the volume of transported freight; - b) for Cooling, maintenance and other auxiliary shops--proportional to the share ~f services provided; _ c) tor compressing, pumping and other shops or power plants--proportional to the - volsme ~f air, gas, oxygen, water, etc. obtained from them; ~ d) for centrai plant laboratories--proprtional to the amount of analysis and the volua,~ of teating carried out in connection with the manufscture of a given type - of product. . - The energy losses in thermal and electric networks and transformers ar~ determined on the basis of experimental measurement$ or are proportional to the consumption of power fox the production of the corresponding types uf goods (or work). The procedure for diatributirg the losses is determined by special methods and inatruc- tions. 3.3. Fixed rates of consumption of thermal and electric power for heating, venti- lation, refigeration, the production of co~npressed air and oxygen., water supply and other secondary needs of industry must be established separately at enterprises and (according to the determination of ministries and departments) associations as well. 3.4. The loases of fuel and thermal and electric power causad by variations in ac- - cepted production technology, operating conditions and formula.s and by nonobservance - - of the requirements for raw materials and stocka as wa11 as other inefficient ~oases need not be included in the fixed rates of conaumption for these resourcea. 3.5. Fixed ratea of consumption for fuel and tl~ermal and electric power in ~he pro- duction of goods (or work) do not include expenditures for the construction an.d major repair of buildings and structures, for the installation, start-up and adju~tment , of new production equipment, for scientific research and experimental operations, 4 - FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 ~ F0~2 OFFICIAL USE ONLY for outside power distribution (for settlements, dining facilities, clubs, day nur- series and ~.indergartens, e~c.) and for fuel lost in atorage and while bsing trans- ported. Th~ rates of consun:ption of fuel and thermal and electric power for these needa muat be established separately. If. in addition to the main product, an enterprise produces semifinished goods which - are suppiied to other enterprises (castings, forgings, atampinge, clink~r brick, eCc.) or goods for public consumption, the expenditure of fuel and thermal and elec- tric power on their manufacture is fixed separately and is not included in the fix~ed ratea of consumption for the manufacture of the main product (work). 4. Units of Measurement for Fixed Rates of Consumption 4.1. The units of ine~.surement for f ixed rates of consum~ tion must correspond to the units of ineasurement used for the planning and accounting of fuel ar.d thertnal and electric power and the voiume ot production items (or ~ork). TheS ~ust also insure the practical feasibility of monitoring the realization o~ these rates. - 4.2. The rates of consumption of fuel and thermal and electric power per unit of production (or work) are fixed: - for furnace fuel oil.--in kilograms and grams (kg, g) of conventional fuel; - for thermal power--in gigacalories and thousands of kilocalories (Gcal, kcal); - electric power--in kilowatt hcurs (kWh); ~ for gasoline, diesel fu~:l, ~et fuel and other petroleum products--in kilograms ana grams (kg, g) of natural or conventional fuel. 4.3. The f ixed ratas of consumption for fuel and therma.l and electric power are es- - tabliahed for tne manufacture of one unit of the finishQd product (a ton ef pig iron, a ton of coal), for a unit of procesaed raw mater ial (a ton of refjned oil) or for a uni~ of work performed (a ton-kilometer, a running meter of penetration, ~tc.). [~.4. When fixing rates of consumption for fuel and thermal and electric power for tha production of a single type of article (or type of work) that varies in campo- sition (or consists of different types of work carried out), conventional units of measure;nent are employed (canned goods--in st~ndard cans; mechanized cultivation-- in standard hectares, e~c.). 4.5. In the machine construction sectors of i,~au3try which manufacture products ac- cording to an extenaive product lis~, the f ixed rates of conaumption of thermal and - electric power are set, in exception to the rule, ~er 100U rubles of net (standard) - or commercial production. For construction, the rate~ are set per 1000 rubles of construction and installr~tion work performed using 1oca1 resources. This procedure is followed in the construction industry and in repair and experimen~al plants at the ministry and departmental level, where it is pract ically impossible tn select ~ a single un~t of ineasurement for production in real or conventional units. It is also foZlc~wed in a.ssociations and enterprises for which productian plans ~.~re ap- proved :in ter~s of cost. 5 FOR OFFICItiL LSE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 FOR OFFICIAL IISE ONLY The f ixed rates of consumptioi~ indicated must be ~t~etera�ined according to the appro- priate procedurea and ins~ructions, taking into acc~unt the planned measu-res for _ energy c~nservation. At the same time, fixed rates o� ,coneump,`.ion for thermaZ and _ electric power for the manufacture of a unit of pro,3uction or fox the arcomplish- - m~nt oi a phyaical amount of wurk, expressed in reaT units, must be eszablished for power-constmaing prc~cesses (founding, forging, heat-t:reating, arG welding, compres- sion of air and oxygen, heating, ventilationr etc.). " 5. Methods for Develoging Fixed Rates of Consumptiou - 5.1. A computed analyticai method is primarily used to develop fixed rates of con- _ sumption for fuel aad thernial and electric powe�r. In addition, emplrical and com- puted str~tistical methods sre also employed. _ Computed analytical and comguted statistical methods are pra:aarily used to deter- - mine group f ixed rates of conaumption for, fuel and thermal and electric power. - - 5.2. 2he computed analytical mPthod provides fc~r determining the f ixed rates of con- sumption of fuel and thermal ar.d electric power by an estimated method. The rates are determir~ed according to item expenditures, uaing progressive indicators for the _ conauaaption of these resources in production. Group fixed rates of consumption for fuel and thermal and electric power are de- _ termined, as a rule, by means of the calculated analytical metho~. The rates are determined as weighted average values, usiag the individual fixed rates of consvmp- tion and the corresgonding volumes of producticm. In individual cases, the group - fixed rates of consumption for the pl~nned year can also be determined on ~he basis of the corresprn~ding r.ates from the base year, taking fnto account the pro~ressive indicators of specific consumption that are achieved and the planned organizational and technical measures that are taken to conserve fuel and power. The individual fixed rates of consumption are determined on the basis di theoretical calculationa and experimentally established rated performance characteristics2 of _ power-intensive units and i:~atallations, taking into accour,t the progressive indi- catora of epecific consuenption of fuel and therma.l and electric power that are achieved and the m~easuras for conserving these resources that are introduced. In order to provide for the developmeat of fixed rates of consuraption, it ia necea- eary to: . - ad~ust the time periods established by the organizations mentioned above. After measures have been taken i'or production improvements associated with changes in equipment parameters and urocesses, power tri,als of the equypment must be conducted. ~ According to the data from these trials, the corresponding power. balances and rated - performance figures for the type of equipment, installatior_ or ~nit can be eatab- iished; _ 2Henceforth the term "rated performaace characterirtic" will be used to describe ~ the depe~dence of the sp~ecific consumption of �uel and thermal and electric powe~ on the load (productivity) of the equipment aia.d upon other factors under normal _ operating conditions. _ 6 FOR OFFICIAL USE QIJ~Y APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 FOR OFFICIAL USE ONLY - car.iy out s;~stematic monitoring, accounting and analysis of the specific opera- ' tional consisn~tion figures for fuel and therma.l and electric power and eliminate inefficient expenditures of fue_ and power. In ~rder to appraise the accuracy of the calculation af the f3xed rate for the sys- tem being used, it is necessary to carry out identical calculations for a year for ~ �~ahich current data are available and then consider the results when determ3ning the - f ixed rates of consumption of fuel and therma.l and electric power for the period = being planned. 5.3. The empirical method for developing individual f ixed rates of consumption con- sists of determinin g the specif ic expenditures of fuel and thermal and electric _ power according to data obtained as a result of testing (experiments). In this - cas~, the equipment ~ust be ad~usted and in proper operating condition. The pro- - duction process must be carried out under conditiona speciiied bq produc~ion ~egu- lations or instructions. 5.4. In those cases when it is not possible to use the calculated analytical and - empirical methads to determine the fixed rates of cansumption, the caleulated sta- - tistical method of establishing the fixed rates of consumption can, as an exception, be emplayed. This method is based upon an analy~is of the statistical data froie - a n~ber of preceding years concern~.ng the actual speci�~.c coneumpti.on of fuel and - thermal and electric power as well as up~n other factors causing variation in the = data. ~ _ 5.5. The baeic reference data for determining the fix~d rates of consumption of fuel _ and thermal and elQCtric power are: - original technical and engineering documentation; ' - production re;ulations and instructiona, experimentally checked power balances - = and rated per;:ormance characteristics of the power and productian equipment, raw ~ materials, technical certificates for the equipment, atandardized indicators which _ describe the most efficient and effective manufacturing conditions (the nower fac- . tcr, the rates of consumption for the power carriers in production, the sppcific ~ thermal characteristics for calculating heating and ventilation exp~ditures, the ~at~s of energy loss durjng transmission and transformation and other indicators); r. - data on the volume and structure of the production of goods (or work); - data on planned and actual specific rates of cons~ption of fuel and power for - previous years as well as documentation verifyiAg the utilization of these data in ~ production; - data fra~ domestic and foreign enterprises engaged in the manufacture of similar - products regarding their advanced experience in the economical and efficient uti- lization of fuel and power and the specif ic rates of consumption ths~ have been achieved. ~ - a plan for organizational and technical measures to conserve fuel and power. 7 FOR OFFICIAL USE ONLY ~ _ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPROVED FOR RELEASE: 2007102/08: CIA-RDP82-00850ROOQ3QOQ5Q032-8 - FOR OFFICIAL USE ONLY 6. Procedure for EstabZishing a Plan of Organizational and Technical Conservstion _ Measures, of Fixed Rates of Consumption and of Programs for the Mean Reduction _ - of These Rates - 6.1. Organizational and technical measures for the conservation of fuel and thermal _ _ and electric power are developed at all administrative levela and are arranged ac- cording to the follo~ing basic guidelines as applied to the productian of goods (or work) in agreement with the established product list: - - the .further development of production technology; - an improv~ment in the utilization and atructure of industrial equipment; " - an increase in the quality of raw materials and the use of types of raw materials that are less energy-consuming; - and other measures (organizat ional, economic, etc.). 6.2. The reference data for the development of plans tor organizational and techni- cal measures to conserve fuel and therma.l and electric power in industry are: _ - a comprehensive 20-year program for scientific a;id technical progress; - a specific overall scientif ic and tectmical program to conserve fuel and power - resources; - basic guidelines far the ecoaomic and social development of the USSR over the next 10 years (in five-year incremeats); - programs for a mean reduction in the f ixed rates of expenditure of fuel and ther- - mal_ :.~.u eiectric power established by the oLgtiniz~~ions listed above for the planned period; ~ - programe for the s,olution of special scientific and technical problems and for - the overall utiliLat:ion of natural resources; - proposals for the utilizatioa of the achievements of scientif ic and technical pro- gress ar~d the resu'~ts of completed acientific researeh and planning and design _ atudies in the economy; - - standards for ttle machines and equipment; - - - results from ~n analysis of the utilization of fuel and thermal and electric power - in industry in pr~vious years; " - power balance~3 at the enterpr ises; - efficiency pzoposals, as well as the results of work on conserving fuel and power resources that Yiave been achieved by leading enterprises, ahops and work crews. During the development of organizational and technical measures to conserve fuel and thermal and electric power, it is necessaxy to appraise the economic effective- nesa of these measures in s�. ef ~ort to select the best method and determine i~s ?x- pediencv, as well as to estatilish the order in which th~se measures are to be intro- duced into industry. ~ i 8 FOR OFFICIAL USE ONLY _ ~ - APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 r0: OFFICIAL USE ONI.Y ~ 6..i. kequi~ement^ tor the mean reduction of che fixed rates of consumption of fuel _ and therma~ and electric powe~ in ir.dustr~,~ are established witnin the plana of eco- nomic and suci~l dei~elopment oi thE JSSR for the ministries and departments or the USSR and the cc.:r.c.1s oi r~~:r_isters o~ the union republics.

This solution was adopted because the reservoir pressure that is comput- ed on the basis of density of the mud that is used in drilling proves basically to be ovarstated. Formation p^essure values obtained by oilfield geopY~ysics methods _ - were not us6d. During the work it became necessary to validate the lower limit of the coefficient of the high anomalousness of formation pressure (ka), since the numerical indicator of this limit was i~o~ 6i^bj-e-valued for various researchers. By k is meant the ratio of formation pressure to the Y~ydrostatic pressure computed conv~ntionally for the same depth. Solution to the question of a lower limit for AVPD can be Wpgz^^ached from two standpoints: that of the highest value of density of the brine water as a result of its mineralization, and that of the conditions for ' drilling wells at stratigraphic complexes in whieh AVPD is absent. If brine waters are examined from the point of view of their maximum mineralization, then it should be noted that the den~ity of even the most highly mineralized waters does not, under the most favorable geological conditions for their appearance, exceed 1.2-1.22 g/cm' (the DD~, the Ciscarpathian trough, and West Ciscaucasia;. On the other hand, in areas where AVPD is unknown, wells are drilled with mud with a density of 1.2-1.25 g/cm'. ~ Theref~re, a pressure that requires weighting of the drilling fluid with hematite, barite, and so on, for the exeeution of normal drilling, must be considered to be anomalously high. Thus, when considering maximal mineralization of the brine waters and the normal conditions for drilling wells without using mud~rveighting materials, 1.2 can be 30 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 ~ FOR OFFICIAL USE ONLY adoptr:d as the lower limit ka of reservoir pressure that is categorized as anemalously Y~igh. The upper limit of this coefficient theoretically should be considered the ratio of overburden pressure to hydrostatic pressure, which is 2.3. The ~.ixthors restrict thenselves in this article to use of the methods of mathemati- , cal statistics, to establishment af the frequency and to distribution of the for- - mation-pressure gradients, and to finding their dependence upon the depth of depo- _ sition of the horizons. For this purpose, all the deposits examined, which relate to the Azov-Kuban' NGO - [oil and gas bearing region], the Ciscarpathian trough, the NGO of the Fergana intermontane depression, the Apsheron NGR [oil and gas bearing district], the Baku Archipelago, the Nizhnyaya Kura NGR, the Balkhan NGR, the Caspian depression, the Black Sea-Crimea, biiddle Ob', Tersa--Sunzha and Tersa-Caspian NGO's, the Lena-Vilyuy NGP [oil and gas bearing province], the Pripyat' depression, the DDV and the - Surkhan-Vakhsh NGO were placed in a field, the bounds of which were the values of the ~ydrostatic and geostatic pressures (figure 1). - In analyzing the chart of formation pressures as a function oi ~he depth of depos- ~ its with AVPD, a number of interesting observations can be expressed. Certain re- searches have previously noted that AVPD is characteristie for depths of more than 3,000 meters, but it is obvious from the chart presented that in some oil and gas bearing regions that are confined to tectonically active geosynclinal fold zones, AVPD begins to appear at depths af just 400-500 meters. Thus, for example, within - the West Apsheron zone, the Baku Archipelago and the Kura lowland of Azerbaijan, - the minimal depths of appearance of AVPD are associated with the crestal portions of uplifts that are complicated by mud wlcanism. Nearly the same situation is ob- served in oilfields of tne Balkhan zone of Turkmenia~ where the minimal depths for the deposits of the red-rock series are noted in the more elevated zones of folds (the Dagadzhik field, 560 meters), in the ~as deposits of the inner zone of the Ciscarpathian fore-trough, and in the fields of the Surkhan-Vakhsh NGO of Tadzhikistan. As is apparent from the chart (see figure 1), some deposits are situated in zones in whicl~ formation~ressure to hydrostatic-pressure ratios approach the value of the overburden-pressure gradient. Thus, of all the depo~its examined, 6 were in the 2-2.1 interval, 4 in the 2.1-2.'L interval, and 2 in the 2.2-2.3 interval (t~ble 1). Thus, only solitary deposits possess maximal ka that is close to overburden (geostatie) pressure. - The distribution of deposits by their position between the hydrostatic pressure (-the density of the water is 1 g/cm') and the overburden pressures (average density of the rock is 2.3 g/cm9) indicates that the frequency of occurrence of deposits with AVPD appears to be as fol2ows, with regard to ka: ?2 percent for 1.3 -1.8, 9 percent for 1.8-~2 and only about 3.5 percent for 2-2.3 (figure 2). Change of ka with depth is of major interest.

It must be supposad that the presaure at which hydraulic fractur- ing of atrata occurs will be close to the maximum value of the AVPD tor a epecifio deposit. - It ahould be noted that, along with AVPD, in deposits situated at depths of more than 4,000 meters, there are also nor.nal pressures that are close to hydrostatic pressures. Thus, for example, in the DDV there are strata with normal pressure where there is AVPD in oil and gas deposits of coal measures. In the Gadyach area, at a depth of 5,109 meters, the ratio of formation pressure to hydrostatic pressure - is 1.08, while in the Upper Poltava area, at a depth of 5,150 meters, the ratio is 1.1, that is, the formation pressure is not anomalous and it almost corresponds to the hydrostatic pressure. - tG ZO`30 40 50 60 ' 10 BO .A'1~M"d The data of well drilling at the Tatar ante- T r~ rT (3) : cline, near the village of Minnibayevo, which , ~ reached a depth of 5,099 meters, 3,215 meters ~p ~ of whicla p~Gsed through rocks of Archeozoic ~ ' age, is of considerable interest, testifying ~ _ ' to the absence of AVPD in crystalline base- . ment rocks.

Old buildin~s~ having historica.l or architectural value~ are being restored so that they will become architectural and historica.l monuments to the _ ol.d days. Old and va.lueless structures are being demolished and in their pl~.ce - ar~ being built new modern buildl.ngs answering high urban development require- ments--Young Pioneer palaces, sports facilities, eommereial complexes~ theaters~ museums, exY,ibition halls~ administrative buildings~ and housing. - - The future llth and 12th five-year plans will also see the creation and further - development of the city, The intensive build-up of the city will continue in accordance with the general plan for the development of MoscoK during the lith and 12th five-year plans. The volume of housing construction will let each inhabitant of Moscow have 12 square meters of living or 19 squa-re meters of total housing space. They plan _ to locate the ba,sic part of the city institutions in the genera.l ci.ty center system and the correaponding district institution~ in the Y~ousing area centers. By 1990 they plan to construct in Moscow a large number of theaters, concert _ and exhi~.i:~on ha11~, museums, palaces of culture and alubs, movie theaters ~ Young Pioneer palaces, libraries, stores~ public dining facilities, hotels, hospital.s, and ather buildings of.a cultural and personal nature. ~ioxever, rloscow is also an industrial center.

Industries which poilute the environment wi].1 be moved out boyond the city limits. ihe housing, municipal and everyda.y buildings, cultural and sports complexes, and industrial enterprises which they inte:~d to construct muat be centrally heated. Thermal power is required for heating, a hot wa.ter supply, ventilation~ cond.itioning~ and the technological needs of industry. The annual heatong load growth ra.te in the 1980-1990 peri.od will be about 4~.5- - 5 percenta The heat load density on the average for Moscow will increa.se to _ 0. ~2 megawatts per year~. 7 gigaca.lories~(hour.s x yea.rs~]. The general trend in supplying heat to the new projects planned for construc- tion in the 19$0-1990 period will be, as in the past ,50 yea.rs, a centralized heat supply based on the combined output of thernial and electric power at a TETS. This trend is l~,sed on conclusions stated S,n the preceding chapters of this book~ namelyi fuel savings, a decrea.se in environmental pollution, creation of high hygienic and comfort conditions for the population, and an inarease of la bar productivity in the power industry. 37 FOR OFF'ICIAL USE ONLY _ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 FOR OFFI~IAL USE ONLY . The following positions have been adopted in determiaiing the lovel of development of centralized heat supply sources in 199o--providia~g 100 percent of the heating, � ventila~;ion, and hot water supply load of the housing, administrative and public, ' - and cultural and peraonal sectors= providing ?0 peresnt of the hp.ating~ ventilationo and hot water supply load of the production sph~re(industrial enterprises~ scien- tilic research institutes~ design bureaus with experimsntal ahops, planning in~~i- tutes, and apecialized higher and secondary educational institutions); the paz~tial - provision ai hea.t for the protective f~rested parkla.nd zone of the cityi the li;a- - ited provision of industrial enterprise steam loads. Under these specified situations they require a centralized heat source capa.city(in - hot water) of about 46,780 megawa.tts(40,155 gigaca.lories per hour) when reta,ining - - a part of the industrial boiler systems to cover a thermal load of about 4,89G megawatts(4,200 gigacalories per hour). 'I'wo options to provide the required thermal poxer for the developm~nt of heat _ sources are being examinedi organ~c fuel and nuclear fuel. The development of organic fuel heat sources is being examined in two sub-options. The first sulr - option is to develop Moscow TETS with the xetention of a centralized heating system coofficient at a level of 0.5-0.6 by the inatallation of centralized heating system Lurbines, mainly the T-250-244, and also the T-100-1 30 and PT-80 turbines. This is the sub-option of the maximum development of centralized heating systems. Nore- ~,ver b~anch TE`TS-9, and T~TS-21 ~ 23, 25, and 26 will atta.in maacimwn expa.nsion. By maximum expansion we mean the maximum possibie nwnb~r of boilers, turbines~ anci PVi:~xpansion unknow~ which can be installed while still maintaining the esta.b- _ 1lshed environmenta.l pollution health sta.ndaxds and the possibility of placing these ma.chine units on the TETS premises. At the same time that they are installing new centra3lzed heating system blocks at - the branch of T~."'TS-9 and at TE'i5-21, 23~ 25~ and 26, they are also considering the - reconstru~tion of TETS-9, il, and 12 by replacing ~he oiosolete and physically worn- ' out machine pa.rts with new ones having a larger unit ca,paci ~y Ril~ high steam para- meters. They envisage completing work on the maximum broadening and reconstruction of the Moscow TETS before 1990. `I'he construction of the Northern TETS is beir.g plan.-~ed along with the widening and reconstruction of the existing Mosco~r TETS. The technical and economic explanatory - d.oc~~ment:, for the Northern TETS will be 42~300 mega~a.tits(36,300 giga.calories per - houx) by the end of 1~90, and the electrical capacit3r--11,260 m~gawatts. Iiesides the TETS in oporation must be �ound 21 existing RTS~xpansion unknow~ ~to include the develop~.ent of their thermal ca.~city to 6, ?00 megawatfis(~~ 750 giga- , calories per hour) and two new RTS with a tota.l thermal capacity of 932 megawatts (800 igaca.lories per hour) . The tota.l ca.pacity of the R1'S amounts to 7, 630 me~a- watts~6 ~ 550 gigaca.lories per hour) . _ 'I'he ahare of covering thermal loads with vartous heat sources in i~yu wiii ue as followss 75 percent from TETS, 15 percent from RTS~ and 10 percent from loca.l sources. By local heat sources we mean building and small city block boiler sy- ` stems.

The rloscow thermal networks have been devel~ped as radia7~ ones. Gr.adually the end sections of the trunk heating systems from the various T~'!'S have beon joined io~e~i~er. However, these end section~~ as a rule~ have relative- ly small pipe diameters~ 4~00-600 millimeters, which s�educe the possibility of the pa.ra.llel working of a Tr;I5 on a common heating trunk and, consequently, of mutual redundancy. At present and in the future the trunk networks, connecting a ;..'~e neighboring T~,~TS to each other, are being built and will be built to include the possibi~ity of mutua.l redundancy~ i.e.~ the practically identica.l pipeline d3ameter over the entire extent of the trunk. This ca.uses an increase in capital - investments in the construction of networks which is justified by an increase in the reliability of the heat supply. Besides an incr.ease in dependa.bility, the opportunity to have two TET5 with diff- - erent economic indica.tors connected makes it possible to cover the summer heating load with the more economica.l equipment of one of the TETS. The question of a reliable and quality heat supply for the Moscow cue~tomers is of paramount import- ance. The following are the basic ways to increa.se the reliability and longevity of the heatin~ main and to have an uninterrupted heat supplys protection of the pipes fram external corrosion, the use of more improved equipment in the thermal n~t- ~ wori.s(fittings, compensators~ pumps~ etc.), the use of more reliable bui.lding ma.~;erials~ the wide use of automation and remote control, an increase in the level of operation and high-quali~y conduct of preventive maintenance and repair work. The most effective way to protect pipelines from external corrosion is to apply a 0 pratective c~at of vitreous enamel to the outer wall of the pipe. By 19s5 they ;~rill. construct several shops for the application of vitreous enamel coatin~s which - will cover the requirerrient for coating pipes with vitic~u~ e:Lamel for repa.ir wor?~ needs. The life of pipelines with a vitreous enamel coverin~r~ according to the most inodest estima.tes~ will double and the cost of constructing the shop will pay _ - fos� itself in one and a half to two years. The pipe-milling plants must Jupply pipes with the coatin~ already on them for the pipelines to be built in the 19~5- 1990 period. 'i'he reliability and economy of transporting heat depends, to a significant degree, on effective and hi~h quality thermal insulation. The search for effective thermal ' insulation materials is being conducted continually. The thermal insulation rna- terials being used now do not fully satisfy the high requirements resulting from di.fficult operati.ng conditions(high humidity and temperature). The insulation, _ especially on large-diameter pipelines, is insta.lled right on the route durin~ the construction work. This does not provide for a high quality work production, i.t reguir~s hi~h labor expenditure, and it lengthens the constLu~tior. time. By 1990 all of the thermal insulation work, with the exception of abutment joints and the individua.l sectors with equipment, must be done at special plants before installatlon. This will significa.ntly increase the quality of insulation insta,ll- .ation, and will decrease labor expendituxe and the length of thermal nstwork ~ consi:ruction. 40 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 APPR~VED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050032-8 FOR OFFICIAL USE ONLY Tho con~,truction of reserve connections will be continued as a way to further in- crease r~:,~liability. Reserve connections tie two or more nei~hboring ~runks to~;eth- ur which permits~ during t:~e emergency switch-off of one from the heatin~ trunk~ - the supply of heat to the customer oveY� the o+~her. The further strengthening of - connections between nea1; sources--T~5 and RTS--will be continued. - The selection of a connection circuit of customers is an important factor in in- crea.sing the xeliability of the heat supply. About 70 percent of the heating load _ is now connected ~y a denendent circuit which does not permit in the return line of the fi,herma.l network an increase of pressure of the ca.st-iron heaters which are at~ove t.he maximum, limited by the mc chanic~.l strength. For this very reason diffi- _ culties arise in the mutua.l redundancy of the heat trunks and when switching the = _ thermal network over to a supply from another heat source. _ _ To ;naint,ain permissible pressure in the return trunk one must, in a number of cases, construct pumpin~; sta.tions and provide for an inereased pipeline diameter which - leads :.o a rise in thermal netxork costs and complicates their opera.tion.
