API Drilling 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.
