Product Description
Downhole Mud Motor for Horizontal Directional Drilling
Product Overview
The downhole mud motor is a hydraulic drilling tool powered by drilling mud flow. Mud stream from the mud pump flows through a by-pass valve into the motor, creating pressure differentials that drive rotor rotation and transmit torque and speed to the drill bit. Performance characteristics are determined by specific property parameters.
Available Sizes & Customization
We provide comprehensive size coverage from 1 7/8" to 26", with popular sizes including 2 7/8", 3 1/2", 4 3/4", 5 7/8", 6 1/2", 7 3/4", 8 1/2", 9 5/8", and 11 1/4". Custom configurations are available for special sizes, high-speed, medium-speed, and low-speed applications based on customer requirements.
Key Performance Advantages
- Dedicated torque transmission directly to drill bit, minimizing drill pipe wear
- Specialized drill tool combinations for large slope applications and continuous control guidance systems
- Linear torque-pressure relationship within operational range for predictable performance
- Hollow rotor design enables high displacement input for improved return velocity and sand carrying capacity
- Compatible with various drill bit types for flexible application scenarios
