JingMei Drilling Motors offers high quality performance mud motors for the drilling industry. We specialize in the sales and rental of quality drilling mud motors and other downhole equipment for all type of drilling applications.
Downhole motor
Downhole Motor is a positive-displacement motor. The high pressure fluid enter into the motor, making the fluid converted into mechanical energy and the motor drive the principal shaft and bit rotating to drill. We can supply a complete line of drilling motor ranging from 3-3/4" OD to 9-5/8" OD, different types and specifications, such as ABH(adjustable bend dousing) and oil based mud or high temperature etc.
Supplier Product code: eg. 7LZ172*7.0
Competitive Advantages of the product:
Increase rate of penetration.
Better hole deviation control.
Reduction in drill string failure rate
Reduction in wear and tear of the swivel, Kelly, and rotary drives.
Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.
Construction
Downhole motors differ in size and performance characteristics, but they share the same basic components as follows:
Crossover Sub
Safety Catch Sub
Power Section
Coupling Assembly
Bearing Assembly
