The super-short downhole motor developed by Orient is capable of effectively reducing the total length of motor and the distance between bend point and spindle nose, which means to shorten the distance between instrument and drill bit. Thus, it ensures the motor power and raises the kick-off rate at the same construction condition. It is also suitable for the occurrence on requirement of high control accuracy on borehole tracking. The existing models contain 95 and 172 etc.
