Description
Downhole drilling mud motor is a kind of downhole drilling tool powered by mud. The mud from mud pump enters motor by way of bypass valve, and a pressure drop between motor inlet and outlet created, such pressure drop will drive the motor rotator to rotate, and transmit the torque and rotary speed to bit by universal shaft and transmission shaft. The downhole motor property mainly depends upon its property parameters.
This product uses the high and new technology of coating to avoid coating off of rotors resulted from the traditional technology. Its strength and life are greatly improved.
Product advantages
- 1.Increased rate of penetration.
- 2.Better hole deviation control.
- 3.Reduction in drill string failure rate.
- 4.Reduction in wear and tear of the swivel, Kelly, and rotary drives.
- 5.Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.
