Adjustable Downhole Motor For Trenchless

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

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.

Non-magnetic downhole motor is a kind of specially designed small size downhole motor. The cross-over sub, power section are all made of non-magnetic material which is usually beryllium bronze. Specially designed material makes the downhole motor is allowed to work with the measuring instrument directly without any connection sub and this also shortens the distance from measuring point to the bit making the measurement more accurate. And beryllium bronze is a very good anti-explosive material which allows the motors works in coal mine directly without any safety crisis.

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.
