| 摘要 |
A drilling motor for directional drilling in a wellbore has a drill bit at a downhole end, a bent housing having a first bend spaced above the drill bit and defining a first angle, the first bend having an inside bend surface and an outside bend surface, and a guide element that biases the first bend toward the first angle when the bent housing is positioned within a straight section of the wellbore. The guide element may be a pad, a centralizer or a second bend in the bent housing. |
