The Characteristics of HDD Hole Opener
Provide rotational and propulsion power: The mud motor utilizes the fluid power of the liquid to transmit force, achieving the functions of rotational driving and mud discharge. By converting hydraulic energy into mechanical energy, the mud motor can transmit power to the drill bit to drive drilling operations.
Structure and working principle: The mud motor is mainly composed of rotating chambers and other components. When the mud or liquid on the drill pipe passes through the rotating chamber of the mud motor, the liquid is subjected to a certain fluid dynamic force, which drives the operation of the motor. Specifically, after the mud enters the mud motor, it forms a screw shape in the rotating chamber, thereby achieving the functions of rotational driving and mud discharge.
