API Drilling Tool 5LZ120*7.0 Downhole Motor Drilling Mud Motor
Description of Downhole Motor
Downhole motor is a kind of downhole 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 downhole motor property mainly depends upon its property parameters.
Dongying provides various sizes of down-hole motors for hole sizes from 1 7/8" to 26". Popular sizes are 1 11/16", 2 7/8", 3 1/8", 3 1/2", 3 3/4", 4", 4 3/4", 5", 5 5/16",5 7/8", 6 1/4", 6 1/2", 6 3/4", 7 1/4", 7 3/4", 8",8 1/4", 8 1/2", 9", 9 5/8" and 11 1/4".
Dongying is able to provide down-hole motors of special size, high-speed, medium-speed and low-speed, according to customer's requirements.
Product Advantages of Downhole Motor
1. The torque generated by the Downhole Motor is only used for driving the drill bit, and reducing wear of drill pipe;
2. It can provide special drill tool combination with large slope, also provide guide drill tool combination for continuous control;
3. The output torque of Downhole Motor has a linear relationship within a certain range with the pressure drop generated by drill fluid through the hydraulic motor.
4. The hollow rotor Downhole Motor can input with large displacement, to improve the up-return speed and sand carrying capacity.
5. It is suitable for option of a variety of drill bits
