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 5):
The bearing section for a positive displacement mud motor of  claim 2 , in which the offset flex drive mechanism comprises:\n a fixed adjustment ring segment fixed to the inside of the outer housing at a location central between the lower end and the upper end; a plurality of electromagnets embedded in an inner surface of the fixed adjustment ring segment; a moving adjustment ring segment, located inside the outer housing at a location central between the lower end and the upper end; the moving adjustment ring segment being movable rotationally within the outer housing from a neutral position on an opposite side of the inside of the outer housing from the fixed adjustment ring segment to a bent position in which the moving adjustment ring segment is in contact with the fixed adjustment ring segment; and a plurality of permanent magnets embedded in a surface of the moving adjustment ring segment which is adjacent to the inside surface of the outer housingwhen the moving adjustment ring segment is in the neutral position and which is in contact with the fixed adjustment ring segment when the moving adjustment ring segment is in the bent position; wherein when the moving adjustment ring segment is in the neutral position, the drive sub rotates between the inner surface of the fixed adjustment ring segment and the moving adjustment ring segment without contacting either the fixed adjustment ring segment or the moving adjustment ring segment; and wherein when the moving adjustment ring segment is in the bent position, the moving adjustment ring segment contacts the flexible drive sub, bending a central portion of the flexible drive sub away from the central axis of the outer housing; the control circuit being electrically coupled to the plurality of electromagnets such that the polarity of the magnetic field of the plurality of electromagnets is controlled by the control circuit, so that when the polarity of the electromagnets is set such that the plurality of electromagnets attracts the plurality of permanent magnets, the moving adjustment ring segment is rotationally moved to the bent position, and when the polarity of the electromagnets is set such that the plurality of electromagnets repels the plurality of permanent magnets, the moving adjustment ring segment is rotationally moved to the neutral position.
