Downhole Screw Meter
The downhole screw motor is a kind of power tool that transforms the pressure of liquid to mechanical energy in the downlole. When the power liquid flows into the screw motor, a pressure difference will be produced between the inlet and outlet of the motor, the differential pressure drives the motor rotating round the stator, provide torque moment and speed to the drill bit, thus the drilling process is being performed. The drill pipe is not rotating during work process, so the advantages are obvious if comparing with conventional drilling system. The downhole screws motor is suitable for vertical, directional and horizontal well.
