The screw drilling tool is a positive displacement mud motor. After the high-pressure drilling fluid enters the screw, the hydraulic energy is converted into mechanical energy, and the rotor drives the main shaft and the drill bit to rotate and the drill bit to drill to achieve the purpose of drilling.
