PDM Thread Drill Spare Parts Directional Drilling Mud Motors 286mm

Oilfield Directional Drilling Mud Motors 43mm-286mm

Product Overview

Downhole Mud Motors, also called Positive-Displacement Motors (PDM), make use of a power generation section which is made up of a rotor/stator combination. In order to move a rotor part, a PDM requires hydraulic power from drilling fluid flowing through the power generation part. With a PDM, the stator and rotor work in tandem in the same way that gears do. The stator acts as the outer gear, and is made from a moulded elastomer featuring at least two lobes. The OD of the elastomer is protected by a secure metal casing. The rotor is positioned within the stator, and acts as an internal gear. This rotor is made of metal, and will have one less gear or lobe than the stator. Because of this difference, a cavity is created which is filled with drilling fluid when the PDM is downhole. This cavity acts as a wedge when it is put under pressure, and because the drilling fluid itself can’t be compressed, the force applied to the top of the wedge causes the rotor to move.

We can produce series of downhole motors in different sizes, as Φ57(21/4"),Φ73(23/4"),Φ89(31/2"),Φ95(33/4"),Φ120(43/4"),Φ127(5"),Φ165(61/2"),Φ172(63/4"),Φ178(7"),Φ185(71/4"),Φ197(73/4"),Φ203(8"),Φ216(81/2"),Φ244(95/8"), etc.

 

Types & 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.
