Detail Features

In drilling the non-conventional wells such as directional wells, horizontal wells, and highly-deviated wells, downhole motor with adjustable bend housing which uses the new coupling design can be adjusted from 0°to 4°at 19 different angles.
Detail Features & Advantages
1. Adjustable Bend Housing
In drilling the non-conventional wells such as directional wells, horizontal wells, and highly-deviated wells, downhole motor with adjustable bend housing which uses the new coupling design can be adjusted from 0°to 4°at 19 different angles. It overcomes the shortcomings of flat universal shaft such as the exposed surfaces are susceptible to erosion and short operational life.
2. New Drive Seal Universal Shaft
The new drive seal universal shaft effectively increases the contact area of transmission components and reduces their contact stress. It helps to increase carrying capacity and service life of the universal shaft.
3. Uniform Wall Thickness Downhole motor/Even wall downhole motor
Through changing the shape of stator housing in a reasonable way, it makes stator's rubber thin and uniform which overcomes the shortcomings of conventional stator technology. The downhole motor with even wall stator has advantages such as high cooling efficiency, rubber thermal expansion, good even sealing effect , broader adaptation range, more optimized structure and lighter overall mass, all of which can improve the working environment and life of downhole motor.
4. High-temperature Motor
The resistant temperature of motor can achieve over 150'C by the using of excellent resistant temperature rubber in the stator. It can meet the requirement of the High temperature well, ultra deep-well.
5. Rotor Surface
The special chrome method makes the layer thickness of the valley and peak same.
The tungsten carbide coating layer of rotor has stronger ability of corrosion and wear resistance, enabling the down-hole motor to work normally in the saturated saltwater mud.
6. Changeable Stabilizer

To meet the requirements of different drilling conditions, we equipped the housing of the drive shaft assembly with different types of stabilizers: Fixed and Changeable ones, etc. We can provide different kinds of stabilizers for customers to choose.

7. High quality thrust bearing and radial bearing

As an important part of downhole motor, our bearings are made of high quality alloy materials. It has the characteristics of long service time, high precision and so on. It is an important part of the reliability assurance of drilling motor.
