It is one kind of positive displacement down-hole motor, with working principle is to convert the high pressure fluid power of mud into mechanical energy for bit rotation. It is widely used in oil field and mine directional well and horizontal well, cluster Wells and vertical Wells, drilling, deflecting, adjusting azimuth, coring, reaming, side tracking and work-over treatment, and also applied in some special operations as compound drilling and traversing, etc.
Down-hole motor is a kind of down-hole dynamic drilling tool upon the power of drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The down-hole motor property mainly depends upon its property parameters.
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 down-hole motor.
