Drilling Downhole Mud Motor

1. About the manual The lake drilling motor is a powerful and reliable positive displacement motor. The motor generates an optimum balance of rotational speed and high torque to drive a variety of drill bits at speeds that maximize tool life and performance. Lake motors offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters. Lake motors are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over). 2. Advantages of downhole motor Increased rate of penetration. Better hole deviation control. Reduction in drill string failure rate. Reduction in wear and tear of the swivel, kelly, and rotary drives. Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.

Downhole motor is a kind of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters. ADVANTAGES OF DOWNHOLE MOTOR Increased rate of penetration. Better hole deviation control. Reduction in drill string failure rate. Reduction in wear and tear of the swivel, Kelly, and rotary drives. Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor. 1. Material: High manganese steel 2. Standard: API 3.

With the help of our team of experts, our company known as a leading Exporter of Drilling Motor in Beijing, Beijing, China.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: 1. Bent drilling motors: The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available. 2.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. 3.Extension drilling motors: On the basis of the ordinary drilling motor, improve motor torque to make the bit drilling quickly by increasing motor stage. 4.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.. 5.Drilling motors with high kick-off rate: Unique structural design, shorter body, bent point closer to the drill bit, and kick-off rate of up to >1°/m. 6.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. 7.High-temperature drilling motors: In order to improve the high temperature resistance of the stator rubber of the drilling motors, to meet the drilling requirements in high geothermal gradient region and deep and ultra-deep well drilling requirements, high-temperature resistant rubber is adopted to increase the temperature resistance of motor above 150ºC. 8.Sealed driving shaft drilling motors: The ordinary mud lubricated driving shaft is replaced with oil lubricated seal driving shaft, which improves the working conditions of the thrust and radial bearings, thus extending the service life of the drilling motors.
