Product Description
DOWNHOLE MOTOR/ MUD MOTOR
1. About the Manual
Roschen Down Hole Motor is a powerful and reliable positive displacement motor. The downhole motor generates an optimum balance of rotational speed and high torque to drive a variety of drill bits at speeds that maximize tool life and performance.
Roschen Down Hole Motors offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters.
Roschen Down Hole Motors are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over).
2. ADVANTAGES OF DOWNHOLE MOTOR
Increased rate of penetration.
Better hole deviation control.
Reduction in drill string failure rate.
Reduction in wear and tear of the swivel, Kelly, and rotary drives.
Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.
3. CONSTITUTION
Downhole motors differ in size and performance characteristics, but they share the same basic components as follows (Fig.1) :
