Audited Supplier 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", 4-1/8", 4-3/4", 5", 5 1/2", 6-1/4", 6-1/2", 6-3/4", 7",7-1/4", 7-3/4", 8", 8-1/4", 8-1/2", 9",9-5/8", 11-1/4".
2.Structure form includes straight, single bend, double bend, angle adjustable 0~3° and so on. Heat-resistant temperature range consist of 250°F (120ºC) or less than 250ºF (120ºC), and between 250 ºF(120ºC) to 355ºF (180ºC). We can also provide all specifications including oil based mud resistant motor and saturated saltwater mud resistant motor.
