Product Introduction
A downhole motor is a tool used in drilling that converts the energy of drilling fluid into mechanical power. When the mud pump supplies mud to the motor, the pressure changes at the motor's entry and exit points, causing the rotor to rotate around the center of the stator. This rotation transfers torque and speed to the drill bit through a universal shaft and transmission shaft, allowing drilling operations. Downhole motors are widely used in drilling and maintenance tasks in oilfields and coal mines.
Product Advantage
The benefits of using screw drilling tools for directional drilling are as follows:
1. Enhanced drilling efficiency: By increasing the number of bit revolutions and torque, screw drilling tools can improve the feed rate and shorten the drilling cycle.
2. Reduced wear and damage: Direct power supply from the well bottom minimizes wear and damage to the drill pipe.
3. Precise orientation: Screw drilling tools enable accurate orientation, slope adjustment, and deviation correction, leading to improved economic efficiency in horizontal wells, clustered wells, and well workover operations.
4. Prolonged tool lifespan: The advanced structure of screw drilling tools enhances their durability, resulting in a longer lifespan.
5. Adaptability to complex geological conditions: Screw drilling tools are particularly effective in challenging geological conditions, such as high rock hardness and steep formation angles, thereby increasing the drilling success rate.
Product Uses
The screw drilling device for directional drilling is an advanced tool with a wide range of applications:
1. Directional drilling: This tool enables simultaneous adjustments to the drilling top angle and azimuth angle, improving precision in hitting the target. It is suitable for various types of strata and can be used in geological exploration, oil extraction, and other industries.
