Luhai drilling motor is a positive displacement motor. High pressure drilling fluid flows into the drilling motors, thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling.

Luhai produces LZ73, LZ89, LZ95, LZ102, LZ120, LZ127, LZ146, LZ165, LZ172, LZ185, LZ197, LZ203, LZ216, LZ244, LZ286 and other types of drilling motors. They are for drilling diameter of 88.9-660mm. Luhai also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties. At present, in addition to ordinary straight drilling motors, Luhai can also provide the following types of drilling motors:

Bent drilling motors: The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available.

Bent angle adjustable drilling motors: The bent angle of the drilling motors can be adjusted on well surface which enhance the extension of kicking off.

Hollow drilling motors: To meet the needs of high flow rate solids carrying in drilling, hollow rotors with carbide nozzles of different sizes are adopted, which can increase the input flow rate and the horsepower of drill bit.

Saturated saltwater mud-resistant drilling motors: To maintain long time operation of drilling motors in saturated saltwater mud, special rotor coating is adopted to provide better corrosion and wear resistance.
