The following is a detailed introduction about LZ185 Down-hole Motor
Down-hole Motor is a type of positive displacement motor, which works by using high-pressure drilling fluid to enter the screw and convert hydraulic energy into mechanical energy. Specifically, the drilling fluid enters the chamber between the stator and rotor of the screw drilling tool under pressure, pushing the rotor to rotate. The rotor then drives the main shaft and drill bit to rotate, thereby achieving the purpose of drilling with the drill bit.
1.Stable power output: It can provide relatively stable torque and speed under different downhole conditions, ensuring efficient drilling operations.
2. Adapt to various geological formations: By selecting different parameters such as the number of motor heads and bending angles, it is possible to adapt to various geological conditions ranging from soft to hard.
3. Easy to operate: The structure is relatively simple, easy to use and maintain, and has high reliability when working underground.
4. Good directional performance: Especially for curved screw drilling tools and adjustable angle screw drilling tools, they can accurately control the wellbore trajectory and meet the requirements of directional drilling and horizontal drilling.
1.Oil and gas exploration and development: Widely used in oil and gas drilling operations, it can be used for drilling various types of wells such as vertical wells, directional wells, and horizontal wells.
2. Geothermal exploration and development: Used for the exploration and development of geothermal resources, capable of drilling high-quality geothermal wells in deep formations.
