Introduction.

Complex solution of geological and technical problems

exploratory drilling of medium and high hardness rocks with large

effect is realized when used to penetrate wells of shells

KSK. Main advantages of SCS over traditional column

drilling consists, first of all, in a sharp reduction in time by

descent and lifting operations (ACT). Due to this, an increase occurs

flight speed, total borehole throughput and

reduced cost of drilling operations. The second advantage of SCS is protection

core from washing with washing liquid and mechanical action with

the sides of the core receiver, since it does not rotate during drilling.

Efficiency of SCS application increases as resistance increases

drilling bits and increasing depth of drilled wells.
