Abstract:
A bearing section for a positive displacement mud motor for directional drilling in which the deflection of the drill bit is remotely adjusted by bending the drive sub using an offset flex drive mechanism to adjust between desired settings. The bearing section is adjustable from the surface without the need for trips of the bottom hole assembly to the surface.

Claim (Index 1):
A bearing section for a positive displacement mud motor, comprising:\n a) an outer housing comprising a cylinder having an upper end, a lower end, an inner surface and a central axis; b) a fulcrum bearing stack mounted inside the outer housing adjacent the lower end, the fulcrum bearing stack having an arcuate inside surface; c) a load transferring bearing stack mounted inside the outer housing adjacent the upper end; d) a flexible drive sub comprising a first end rotationally mounted inside the outer housing by an arcuate section mating with the arcuate inside surface of the fulcrum bearing stack, a second end rotationally mounted inside the outer housing by the load transferring bearing stack, and a length having a rotational axis between the first end and the second end; and e) an offset flex drive mechanism centrally mounted within the outer housing, having a neutral position in which the rotational axis of the flexible drive sub is aligned with the central axis of the outer housing and a bent position in which the offset flex mechanism bends a central portion of the flexible drive sub away from the central axis of the outer housing, causing the rotational axis of the flexible drive sub to form a curve such that the rotational axis of the flexible drive sub at the first end of the flexible drive sub is at an angle to the central axis of the outer housing.
