Under their power conditioae a 250-kilo~+att motor, a 95-kilowatt dri7."a.ia~, orator,
tuft a 300-kiiaeatt tranaformtr were considered normal and sufficiea~ for rlri].ling
e-lren 1,000-after rails. Increasing the power of the electrical equipment vas not
considered expedient, since it uasvoidgbay resulted in underlording, which causer
unnecesrary darsrr add a loNer paver fertar.
Duping the torrent year the Krasnokamekneft' has euttk one inclined and one vertical
sell, both productive, and is now engaged in dril~.ing an exploratory Kell. Work was
carried out at high epees, involving a neK drilling technique asld special operatring
aonditionr for mechanical and electrical drilling equipment.
The vertical yell, Po 53, gunk by speed t.ubine driL'ing, vsa fintahed in 29 days..
The following are th! essential etatiatics concerning this Kell:
It took 697.7 hours ~c reach a depth of 1.020 meters. The artusl.drilling occupied
191. j3 hours as compared to the norm of 407.8 ho:u:e. Thee, the norm xas aurpapsed by
282.6 percent. The greatest di~taace drilled after Betting up the dig vas 14b meters.
Time consumed in raising and lo~etria.g operations 1mder geaerel drilling canditi,ans
amounted to 100 -200 percent of the norm. i'he crew on well 'io 53 P~ ~ e tot+sl of
84.13 hours in loi+ariag the tool, as compared to the norm of 62.2 hours, while g4.E
hours wax spent is raising the trcl, se against the norm of 69 hours. It meat be re-
marked, howeveY, that failure to fulfill the norm in raising sad lowering apezatians
was not a result of insufficient speed Ln the operations themeelve9, bnt was due to
the tine taken up Ly eubeidiary operations pzeparstory to raising awl ].overing.

The normal current fora 300-kllawatt motor is about 38 amperes; thud, the motor w+sp
ogerloaded Pram 50 to 100 percent beyond It normal rating during that time. Such over-
loading cf tie motor resulted from the voluminous feeding of e].ay aortae at high prxerare
and, particularly, from the content of la~.?ge fragments of rock in the slay amrtar wae$?d
out of the vtll iu this method of drilling.
A gradual change in tht method, then, would have been needed for the pzoteetiogi of
the motor, but to determine the power required fpr the sinking of well and the ptnetration
capacity of the drill, this ayetesn wa? II!91n+,.incd dp11y, even at the ri+~k of a motor

the pumping mxcrroz, lowering it to 40-~ ~0 ~perts, but 1t also ;educed the rats of

it Rcet be remarced that 3iK1-kilorrolt-e~pere+? drllli:,g-r,~achiae trans:orwrr are
forced to run with sn ocarl.osd fos frequen+, short-te:m pbxlads. It is oDHoae that the
transfoamer will becane o^erloaded whin the redaction motors are everload+.d.
Special consideration awt hen be given the 3~illi~g-macbine tsasusfoners produced
in 1947 and 19b8. 'Phew transformers are equipped with high-voltage windings beaanss
of Lhe coupler coils which Hake it difficult tc cool overheated windings rN.th oil.
This typo of winding also demonstrated vtry poor resistants to dynamo strain exerted
oa the tolls daring overloading.
Five transformers of this type were esaploytd xith drilling ma.,-,blase for periods
of nom 2 weeks to 1~ months, after which they all broke dGwn. Iuspeetion of the
defective windings revealed in every case, 3ietention a?d multiple ~vpt~ee, as yell ae
esrbonizati~~n o1 Lhe insulation cn the inteaior yarte.
Rewinding of the toile by the loce;.l station technicians wens not eatiefactory, and
the tenet was therefore obliged at that Sine ro rewind tho high-voltage coils of the
drilling-'whine transformers, deice lt_eyt?.lfil~"1dna1 disks, as was done in the drilliag-
iach n~ transformers produced previondly.
It mtet be concluded that a 300-kilovolt-ampere traneiormer with complex coils 1.e
rdt euitauiE for continuous drilling nor, is particular, for high-speed drilling, e!nce
these transformers are designed for uniform loading; and short-term ar9 eoaxetiaxe heavy
overloading of drilling-machine Iraneaormero is unavoidable,
The expenditure of electric energy per meter drilled during high-speed drilling
proved very interesting. Ia the producing sclined well, Po 224, l,^02 meters dsep,
70 kil~rstt-hours were expended in cutting one meter; sad is t':_~ ezpioratory arell,
Fo 31.,, 870 meters deep, 72 kilowatt-h.ure were eapended iu cutting ore mater.
The norms eatabliehtd fur tht trust are 130 kilowatt?ho:irs per mt.flr of costing
for wells up to 1,000 meters deep. This ncrm was coasiderc3 very difficult to fulfill
and even under the very beet cosditio::s 'before the introdnct.ion of speeii-d:i:=.ing
ar_thode the e]zc~.rical e.iergy expended approached 110 kilowatt-hours per aster dri].1e8.
