Positive-Displacement Motor / Mud Motor Thread 5 1/2"REG
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.
Corrosion-resistance:
After corrosion spraying to form special coating, the rotor is better corrosion, erosion and abrasion-resistant. And downhole motor is suitable for long time in the corrosive fluid.
Air Drilling
Air drilling can protect reservoir well, improve rate of penetration, significantly shorten drilling period, take precaution against mud loss and borehole collapse, now is gradually widely used. Air drilling downhole motor is driven by gas, foam and other compressible fluids, provide power for the downhole and drives bit to penetrate rock. Air drilling downhole motor has higher technical requirements of the assembly structure, linear design of the motor stator and operation specification.
