    摘要: An adjustable drilling motor includes a center housing having a connection at each longitudinal end for coupling to a respective bent sub. The connections each subtend a same angle from a centerline of the center housing. The angles are in a same. A bent housing is connected to each end of the center housing. Each housing has a connection at one end for coupling to the center housing. Each bent housing subtends a selected angle. The motor includes makeup rings having a selected thickness disposed between each bent housing and the center housing whereby selected angle magnitude markings on each bent housing correspond to adjacent markings on the center housing when each bent housing is assembled to the center housing to a predetermined torque.
