[0002] Screw drilling tools are a type of volumetric downhole power drilling tools that use drilling fluid as a driving force and convert liquid pressure energy into mechanical energy. When the mud pumped out by the mud pump flows through the bypass valve into the motor, a certain pressure difference is formed at the inlet and outlet of the motor, which drives the rotor to rotate around the axis of the stator, and transmits the speed and torque to the drill bit through the universal shaft and the transmission shaft, thereby realizing the drilling operation. In the petroleum, geological exploration, construction and other industries, screw drilling tools are widely used as an important drilling tool.
