Downhole motor is a kind of downhole power frilling tools by mud. The mud output by the mud pump, will enter the motor through the bypass valve, and a certain pressure difference will be formed at the inlet and outlet of motor, to push the rotor of motor to rotate, and to transfer the torque and the RPM to the drill bit via the universal shaft and the driving shaft.
Drilling downhole motors offer a wide range of configurations to meet different needs. These motors have the power, torque, and speed to drill with the PDC bits for specific downhole conditions or well designs. Using the latest available technology and materials, the motors can be used in an extensive range of drilling applications, such as:
Vertical, directional, and horizontal wells
High temperature

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.Description of downhole motor



1.The down-hole drill motor is a kind of downhole drill tool driven by mud.

2.As mud fluid from the mud pump enters the motor via the bypass valve, a certain pressure difference is formed at the inlet and outlet of the motor, pushing the rotor to rotate. Torque and rotate speed are transferred via the cardan shaft and the driving shaft to the bit.

3. Performance of the down-hole drill motor depends mainly on performance parameters of the screw motor.

4.This product uses the high and new technology of coating to avoid coating off of rotors resulted from the

traditional technology. Its strength and life are greatly improved.

5.It is applicable to directional drilling,horizontal drilling, composite drilling, cluster wells, sidetrack wells and well

workover etc.


3. Advantage 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.

3. Usage:



It is one kind of positive displacement downhole motor, with working principle is to convert the high pressure fluid power of mud into mechanical energy for bit rotation. It is widely used in oil field and mine directional well and horizontal well, cluster Wells and vertical Wells, drilling, deflecting, adjusting azimuth, coring, reaming, side tracking and workover treatment, and also applied in some special operations as compound drilling and traversing, etc.



Specifications We can produce series of downhole motors in different sizes, as 57(21/4"),73(23/4"),89(31/2"),95(33/4"),120(43/4"),127(5"),165(61/2"),172(63/4"),178(7"),185(71/4"),197(73/4"),203(8"),216(81/2"),244(95/8"), etc.
