Down Hole 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,Website:, 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. 1. It is one kind of positive displacement downhole motor, with working principle is to convert the high pressure fluid power of mud into mechanical energy for bit rotation.2. 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 workover treatment, and also applied in some special operations as compound drilling and traversing, etc. ADVANTAGES OF DOWNHOLE MOTORIncreased 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 steel2. Standard: API3. Advanced technology: With advanced international technology level and design, we can produce all kinds of downhole motor, such as replaceable cylinder centralizer downhole motor, large power downhole motor, meeting drilling well usage downhole motor and so on.4. Features: Big torque, high effective, wide flow rate range, running stable and long using time.5. Specifications: Fit for 3 1/2"--17 1/2" well hole, including straight body, single- bent and double-bent construction.
