Product Description
Downhole motor (or drilling motor , mud motor) is a kind of downhole dynamic drilling tool upon the power of drilling mud (or compressed gases) ,which is a kind of positive displacement motor (PDM). Downhole motor is widely used in construction operations in the oil fields, geology, coal, salt water wells and other industries. Dynamic medium produces pressure loss at both inlet and outlet of the downhole motor, to push the rotor of downhole motor into rotating, and to transmit the torque and speed onto the bit by cardan shaft and transmission shaft.
Downhole motor tools can be used in conjunction with roller cone bits, diamond bits and other special bits for drilling vertical well, directional well and horizontal well.
