METHOD AND ARRANGEMENT OF IMPROVED HORIZONTAL-INCLINED DRILLING ASSEMBLY Russian patent published in 2010 - IPC E21B7/02 E21B7/04 

FIELD: oil-and-gas industry.

SUBSTANCE: method and arrangement of improved horizontal-inclined drilling assembly for well drilling through underground rocks formations using a drill pipe, includes the drill pipe or a drill string descending into the well and its later lifting up. The drilling assembly includes a power aggregate for its power supply, a support frame, which can move between in parallel to the rock and in perpendicular to the rock positions, and the support frame moving device. A rotor block and a carriage aimed to transfer rotation, axial and return towing (lifting) forces to the drill pipe. The drilling assembly aimed for wells drilling with use of the drilling pipe through underground rocks formations, with any angle relatively to the underground rocks, between in parallel to the rock and in perpendicular to the rock positions. The method includes the drilling pipe dislocation on the drilling assembly, the support frame movement in setting it in the required drilling angle, the rotor block and carriage movement till it have contact with the drilling pipe, transfer rotation, axial and return towing (lifting) force to the drill pipe and underground rocks formations drilling with the drilling pipe.

EFFECT: invention provides power increase for the rotation drive and easy transportation.
