Downhole mud motor

High safety reliability; Long working life; competitive price; quality after-sales service

The downhole motor is a positive displacement motor. It converts the high fluid power of drilling fluid into mechanical energy for bit rotation. Downhole motors are widely used in the drilling, kick-off, azimuth control, coring, reaming, sidetracking and workover for the directional wells, horizontal wells, sidetracked wells and vertical wells of oilfields and coal mines. In addition, the down-hole motors are suitable for combination drilling. Now we can provide various sizes of down-hole motors for the sizes through 3-1/2"~17-1/2". Popular sizes are 2-7/8", 3-1/8", 3-1/2", 3-3/4", 4", 4-3/4", 6-1/2", 6-3/4", 7-3/4", 8", 8-1/2" and 9-5/8". We can supply down-hole motors of special specifications, high-speed, medium-speed and low-speed down-hole motors upon customer’s special requirements.
