Our deflecting tools have two types: anchor type deflector and hydraulic setting slip type deflector. hydraulic setting slip type deflector supply accurate orientation solid seat sealing advantages etc.

When reservoir area casing seriously damaged or reservoir sand buried or collapsed, the well can't production, in order to use the upper casing, reduce the cost of drilling, can make window cutting sidetracking on the upper casing above oil layer, to form a new hole for drilling.

Internal window sidetracking is a crucial method when drill a deviated well with seriously damaged bottom casing, to use the upper casing, make the well build up production capacity.

Window sidetracking tools mainly including deflector and window milling taper.

Basic Parameters and Performance Indicators

API Drilling Chinese Downhole Drilling Mud Motor is a kind of downhole drilling tool powered by mud. The mud from mud pump enters motor by way of bypass valve, and a pressure drop between motor inlet and outlet created, such pressure drop will drive the motor rotator to rotate, and transmit the torque and rotary speed to bit by universal shaft and transmission shaft. The downhole motor property mainly depends upon its property parameters. 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. It is applicable to Horizontal Directional Drilling, composite drilling, cluster wells, sidetrack wells and well workover, Coiled Tubing Operation, etc.   downhole drilling motor

Downhole motor is a type of positive- displacement downhole motor(PDM). After high pressure drilling fluid enters into downhole motor from drill stem, fluid pressure forces rotor to rotate that transfers torque to bit to achieve drilling purpose.

Various downhole motor assemblies for well size 1 7/8"~26" with 24 main dimension specifications (which are identified by outer diameter of stator) : 1-11/16", 2-1/8", 2-3/8", 2-7/8", 3-1/8", 3-1/2", 3-3/4", 4", 4-1/8", 4-3/4", 5", 5-1/4", 5-7/8", 6-1/4", 6-1/2", 6-3/4", 7-1/4", 7-3/4", 8", 8-1/4", 8-1/2", 9", 9-5/8", 11-1/4".

Structure form includes straight, single bend, double bend, angle adjustable and so on. Heat-resistant temperature range consist of 250°F (120℃) or less than 250℉ (120℃), and between 250 ℉(120℃) to 355℉ (180℃). We can also provide all specifications including oil based mud resistant motor and saturated saltwater mud resistant motor.

Outstanding Features

Various rotation rate and torque, high efficiency, wide flow range, smooth operation, easy maintenance, high reliability, long service life.

Safe Application

Adequate strength and specially designed multiple falling-off-proof devices to ensure safe drilling operation.

The ordinary downhole motor consists of the following components:

(1) Float assembly or By-pass valve assembly

(2) Rotor anti-drop assembly

(3) Power section assembly

(4) Universal shaft assembly

(5) Bearing assembly

In addition to ordinary downhole motor, the following components for special purpose are available to make up steerable downhole motor to meet various requirements of drilling operation:

(1) Directional joint

(2) Bend joint (fitted above or below by- pass

valve to make up single or double bend downhole motor)

(3) Hollow by-pass power section

(4) Fixed Bend Housing (with 0~3°fixed angle)

(5) Adjustable bend housing

(6) Housing stabilizer on bearing assembly

(7) Changeable stabilizer

(Of course, customization is also allowable, as long as you can provide detailed drawing, especially some parts like bearings.)

Each downhole mud motor is tested on the professional testing bench and the delivered downhole mud motor is 100% guarateed qualitified, then the test report will be provided to you.

Each downhole mud motor can continuously work 7~10 days with good working condition and correct operation. 

Of course, online after-sale service is also available at any time.
