Screw downhole motor drilling equipment

Downhole motor is a king of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the outlet of mud pump flows through a dump value into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the motor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters.
We can supply difference types of downhole motor, from 60 to 244mm in diameter, 3.5MPa, 7MPa and 14MPa pressure series, including single lobe and multi-lobe, single bent and double bents motors, which can match different kinds of stabilizers. Chinese manufacturers have the ability to develop a variety of down-hole motors in independence.
