API Downhole Screw Oil Drilling Motor 430r/M 4.0Mpa
API Oil Drilling Motors / Downhole Screw Motors Lobe 5:6
Product Descrption
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.
Benefits of Oilfield Downhole/Mud 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.
