Description
Downhole Motor is a downhole dynamic drilling tool that fluid pressure energy is converted to mechanical energy driven by the powerof drilling mud. Mud stream from the outlet of a mud pump flows through a by-pass valve into the motor, the stream produces pressure loss at both inlet and outlet of the pump to push the rotor into rotating, also transmit the torque and speed onto the bit, thereby drilling operation. The downhole motor property mainly use to deviated well and horizontal well.
