摘要
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.
