Abstract

FIELD: oil borehole drilling. SUBSTANCE: device has body 4, two supporting members 7, hydraulic chamber 5 and valve units 13 with drive 14. Hydraulic chamber 5 is situated between supporting members 7 and connected cavity of body 4 and atmosphere through valve units 13. Hydraulic chamber 5 has main horizontal part and secondary vertical parts 11, placed on its ends. Supporting members 7 are interconnected in their middle by rod 8 with piston 6. Piston 6 is set in the main part of hydraulic chamber 5. Valve units 13 are made as interconnected piston 16 by pulling 15. Pistons have two rows of canals. Drive 14 of pistons 16 is set on the pulling. Partitioning pistons 12 are located in secondary parts of the hydraulic chambers. During device deepening into a borehole supporting members 7 are in transportation position. Before the drilling starts the device is orientated. Then a signal is sent to drive 14 of valve units 13. Pistons with two rows of canals start moving under action of drive 15. One of secondary parts of the hydraulic chamber at that time is hydraulically connected with atmosphere. The other secondary part of the chamber is also connected with atmosphere through body 4. Rod 8 and piston 6 under pressure of cleansing liquid is moved to the edge position and body 4 due to interaction of supporting members 7 with borehole wall will displace from the borehole axis. EFFECT: control of trajectory of a slant directed borehole. 3 dwg
