Product Description

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).

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 motors differ in size and performance characteristics, but they share the same basic components as follows (Fig.1) :

Mud motor, Downhole Motor used for HDD machine Rock conditation Drilling, Rock tools

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.

A Variof Types &ety the Capabilities In accordance with the actual drilling needs, we push out high, midiem and low speed downhole motors, of a variety of types with different functional configuration and application for all working conditions.

1. Standard type Standard motor, mud lubricating transmission shaft, straight, single and double bent.

2. Long type The torque is increased by 30%to 60%than standard ones, mud lubricating transmission shaft, straight, single and double bent.

3. High flow rate type The adoption of hollow rotor and different sizes of hard alloy jet nozzle to increase the incoming flow and bit power.

4.High deflection type The unique structure design makes the overall length shorter and bent housing closer to the bit, deflection rate reach up to 1/m, so as to keep good working conditions.

5. High temperature resistance type The motor stator is made of superior quality high temperature resistant rubber, which enables the motor to perform stably in the well bottom at max. 175 C.

6. Oil-stransmission shaft type ealed It improves the working condition of thrust bearing and radial bearing, and increases the life span of each single trip.

7. Bend angle adjustable type We equip the motors with adjustable bend housing in different types and sizes, and through which before dropping we can adjust the bend angle.

8. Saturated saltwater mud resistance type The special coating on the rotor with strong ability of anti-corrosion and wear-resistance enables the motor to work stably for a long time in the condition of saturated saltwater mud.

9. Impact Resistance Type We adopt a series of shock absorbers to lighten or eliminate bit jumping and impact shock occurring in drilling, protect the drilling tools avoiding damage, increase service life and ensure the drilling safe and efficient.
