LZ127 down-hole motor is a common downhole power drill. The following is its introduction
The down-hole motor is a volumetric motor. After the high-pressure drilling fluid enters the screw, a certain pressure difference is formed at both ends of the motor, which drives the motor rotor to rotate, and transmits the torque and speed to the drill bit through the universal shaft and the drive shaft, driving the drill bit to drill, thereby converting hydraulic energy into mechanical energy.
It is mainly composed of four parts: bypass valve assembly, motor assembly, universal shaft assembly and drive shaft assembly.
1. High temperature resistant technology. It solves the problem of stator rubber debonding and aging at high temperature, and the service life of a single downhole is more than 80 hours.
2. Ultra-long life design. In response to the needs of ultra-deep well drilling, the down-hole motor has strengthened the wear resistance of the bearing group and the transmission shaft in the structural design, effectively extending the continuous operation time underground.
3. Accurate trajectory control capability. The new generation of LZ127 down-hole motor are generally equipped with adjustable angle elbows. By optimizing the angle design and mud parameters, the drilling of some inclination increase sections and stable inclination sections can be successfully completed in one trip, and the directional cycle is shortened by 37.6%.
