Description
The downhole motor is a kind of downhole power frilling tool by mud. The mud output by the mud pump will enter the motor through the bypass valve, and a certain pressure difference will be formed at the inlet and outlet of the motor, to push the rotor of the motor to rotate, and transfer the torque and the RPM to the drill bit via the universal shaft and the driving shaft.
Drilling downhole motors offer a wide range of configurations to meet different needs. These motors have the power, torque, and speed to drill with the PDC bits for specific downhole conditions or well designs. Using the latest available technology and materials, the motors can be used in an extensive range of drilling applications, such as Vertical, directional, and horizontal wells; High temperature; Synthetic-, oil-, and water-based mud systems; Performance drilling; Extended-reach wells.
