PDM Drill(downhole Motor)
The downhole Motor is a type of downhole power tool which takes power from the fluid and then translates fluid pressure into mechanical energy. When power fluid flows into the hydraulic motor, the pressure difference built between the inlet and outlet of the motor can rotate the rotor within the stator, providing necessary torque and speed to the drill bit for drilling. The screw drill tool is suitable for vertical, directional and horizontal wells.
