Downhole motor is a positive displacement downhole power drilling tool that uses drilling fluid as power and converts liquid pressure energy into mechanical energy. When the mud pumped out by the mud pump enters the motor, a pressure drop is formed at the inlet and outlet of the motor, pushing the rotor to rotate around the axis of the stator, and transmits the torque and speed to the drill bit by universal shaft and transmission shaft, thereby realizing drilling operation. Downhole motor is extensively used in drilling and workover for oilfields and coal mines.
Assuming the same downhole motor size and fluid volumetric flow rate through the motor (same hydraulic power), the basic differences between the five typical lobe configurations given in F are:
•The higher the lobe configuration, the higher the rotor shaft output torque.MODEL NO. | OD | OD | Rotor End | Stage | Flow Rate | Flow rate |
