Downhole Mud 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. 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. 1. Material: High manganese steel 2. Standard: API 3. Features: Big torque, high effective, wide flow rate range, running stable and long using time. 4. Specifications: Fit for 3 1/2"--17 1/2" well hole, including straight body, single- bent and

1. About the Manual The Lake Drilling MOTOR is a powerful and reliable positive displacement motor. The 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. LAKE MOTORS offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters. LAKE MOTORS are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over). 2.Description of downhole motor 1.The down-hole drill motor is a kind of downhole drill tool driven by mud. 2.As mud fluid from the mud pump enters the motor via the bypass valve, a certain pressure difference is formed at the inlet and outlet of the motor, pushing the rotor to rotate. Torque and rotate speed are transferred via the cardan shaft and the driving shaft to the bit. 3. Performance of the down-hole drill motor depends mainly on performance parameters of the screw motor. 4.This product uses the high and new technology of coating to avoid coating off of rotors resulted from the traditional technology. Its strength and life are greatly improved. 5.It is applicable to directional drilling,horizontal drilling, composite drilling, cluster wells, sidetrack wells and well workover etc. 3. Advantage 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.

API DPM Downhole Mud Motor API Drilling Chinese Downhole Drilling Mud Motor is a kind of downhole drilling tool powered by mud. The mud from mud pump enters motor by way of bypass valve, and a pressure drop between motor inlet and outlet created, such pressure drop will drive the motor rotator to rotate, and transmit the torque and rotary speed to bit by universal shaft and transmission shaft. The downhole motor property mainly depends upon its property parameters. This product uses the high and new technology of coating to avoid coating off of rotors resulted from the traditional technology. Its strength and life are greatly improved. It is applicable to directional drilling horizontal drilling, composite drilling, cluster wells, sidetrack wells and well workover etc
