Down-hole motor/Mud motor is a positive-displacement motor(PDM), the high drilling fluid enters into the high fluid power converted into mechanical energy, and the rotor drives the principal shaft and bit rotating. We provide the Down-hole motor/Mud motor with diameter from 45mm to 286mm, vertical, single-bend, double-bend and adjustable motors; the hear-resistance temperature ranges are ≤120℃,120-150℃; oil-based mud resistance and saturated saltwater mud resistance motors. And we also design and manufacture according to customers' special requirements:1. Bent Down-hole motor: The bent angle on the universal axis can fit curvature of kicking off, Single-bent and double-bent are available.
2. Bent angle adjustable down-hole motor: The bent angle of the down-hole motor can be adjusted on well surface,which enhances the extension of the kicking off.
3. Extended down-hole motor: On the basis of the common downhole
motor, the torque can be increased with the step increasing for the motor.the bit drilling quickly.
4. Hollow rotor down-hole motor The adoption hollow rotor for different sizes of hard alloy jet nozzle the inputting flux and horsepower of drill bit.
5. High kick-off down-hole motor: The curvature of kicking-off can achieve l°/m with the particular design.the shortness length of the whole and adjacent adjacent bend to the bit.
6.Saturated saltwater mud resistant down-hole motor The special coating layer of rotor has stronger ability of corrosion and wear resistance. enabilng the down-hole motor to work for a long time in saturated saltwater mud.
7.High temperature down-hole motor The resistant temperature of motor can achieve over 150°C by the using of excellent resistant temperature rubber in the stator. With the ability of the resistant temperature rubber in the stator, the requirement of the deep-well.up
deep-well and high temperature grads areas drilling can be satisfied.
8.Sealed transmission shaft down-hole motor:Converting the mud sealed to the oil sealed of transmission shaft,this improves the condition of thrust axletree and radial axletree, make the whole down-hole motor life long.
