Horizontal Directional Drilling Mud Motor


Horizontal Directional Drilling Mud Motor

Short Description:

Downhole motor is a positive displacement downhole power drilling tool, which is powered by drilling fluid and coverting fluid pressure into mechanical energy. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss between inlet and outlet of the motor to push the motor rotating around the stator’s axis, then transmits rotation speed and torque to the bit by universal shaft and drive shaft to implement the well operation.
LANDRILL can supply many types mud motor to meet clients’ different drilling condition.

Product Description

ERT(Even Rubber Thickness): 
Reasonable to change the shape of stator housing, the stator elastomer layer of Uniform Thickness downhole motor is thin and even. The characteristics of the downhole motor are short length, high power, high pressure drop, low rotate speed, high cooling efficiency, even thermal expansion, more widely used, more optimized structure and the lighter mass. Especially, the characteristics can prolong downhole motor's life and improve drilling efficiency in the ultra-deep well, directional well and high temperature well.

Resistance High-temperature And Oil Based Mud: 
The downhole motor is suitable for high-temperature, high oil base mud system. In the conditions of less than 180°C and high oil, specially formulated stator elastomer owns high retention rates of strong force strength, tear strength and other properties. The oil-resistant elastomer with reasonable magnitude of interference has better using effect in the high-temperature, high oil base mud.

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 being 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.
