DOWNHOLE MOTOR

Downhole Motor

Downhole motor is a kind of downhole dynamic drilling tool drove by the power of drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters.
