FIELD: oil-and-gas production.
SUBSTANCE: proposed system comprises borehole assembly 18 including top section 22 and control section 24. Shackle 26 extends through top section to adjust axis of control section 24 relative to that of top section 22. Borehole motor allows driving control section 24 via said shackle relative to top section 22. Set of drives 23 to control orientation of control section axis relative to top section axis is mounted on one of said control section 24 and top section 22. High-speed sliding contact is arranged between drives 34 and another section of control section 24 and top section 22.
EFFECT: simple and efficient configuration.
