The following is a detailed introduction about LZ178 Down-hole Motor
The mud liquid pumped out by the mud pump flows through the bypass valve into the motor, forming a certain pressure difference at the inlet and outlet of the motor, pushing the rotor of the motor to rotate around the axis of the stator, and transmitting the speed and torque to the drill bit through the universal joint and transmission shaft, thus achieving drilling operations.
Bypass valve assembly;
Motor assembly (stator and rotor);
Universal joint assembly;
Transmission shaft assembly.
1. Oil and gas exploration and development: Widely used in drilling operations such as directional wells, horizontal wells, and extended reach wells, it can improve oil and gas recovery and reduce development costs.
2. Geothermal resource development: Used for drilling geothermal wells, which can efficiently penetrate geological formations and obtain geothermal resources.
3. Geological exploration: In geological exploration work, it can be used to obtain underground rock samples, understand the stratigraphic structure and geological structure.
