Oilfield drilling Positive Displacement Motor screw drilling tools
Screw drill is a kind of positive displacement downhole power drill, which takes drilling fluid as power and converts hydraulic energy into mechanical energy. When the pressure mud pumped by the mud pump flows through the bypass valve, the flow pressure closes the bypass valve, and then flows into the motor, forming a certain pressure difference at the inlet and outlet of the motor, driving the rotor to revolve and rotate around the stator axis, and transmitting the speed and torque to the drill bit through the cardan shaft and transmission shaft, so as to realize drilling and workover operations.
