Name: LZ203 Down-hole Motor
Brand: SHANDONG SAIGAO GROUP CORPORATION

General introduction of LZ203 Down-hole Motor

LZ203 screw drilling tool is a positive displacement motor and a new type of downhole power tool. It utilizes the hydraulic energy of high-pressure drilling fluid to convert it into mechanical energy, using various drilling fluids such as oil-based mud, emulsified mud, and clay mud as power fluids. It has strong adaptability and can be used for drilling operations in special wells such as horizontal wells and cluster wells.

Product features of LZ203 Down-hole Motor

1.Speed is proportional to flow rate: The input flow rate of drilling fluid is proportional to the output speed of the drilling tool, making it easy to adjust the drilling tool speed by controlling the flow rate of drilling fluid.

2. Linear relationship between torque and pressure drop: The output torque of the drilling tool is linearly related to the pressure drop generated by the drilling fluid through the motor, which is conducive to adjusting drilling parameters reasonably according to the actual situation underground.

3. Reduce drill pipe wear: The rotational power of the drilling tool is only used to drive the drill bit, reducing drill pipe wear, simplifying operations, improving drilling accuracy, and saving drilling power.

4. Good output characteristics: Low output speed, high torque, long pure drilling time, suitable for drilling operations in various formations.

5. Good drill bit flushing effect: The pressure drop of the drill bit water hole is high, and the drill bit water power is high, which can flush the drill bit clean and prevent mud from clogging the drill bit.

Application areas of LZ203 Down-hole Motor

The LZ203 down-hole motor is suitable for oil and gas drilling projects under various geological conditions, especially in well sections that require high torque output and good directional control, such as directional wells, horizontal wells, and drilling operations in complex formations. At the same time, it is widely used in the development of unconventional oil and gas resources such as shale gas, which can meet the characteristics of long horizontal sections and high trajectory control requirements of shale gas wells.
