Product Description
Shock absorber is mounted on the drill column close to the drill bit. In the drilling process, it can also reduce or absorb the vertical and radial vibration of the drill column, and
eliminate the shock loads to reduce the damage of the bit, drilling tool and ground equipment, and to achieve the best combination of drill bit pressure and revolving speed, which protects the down hole motor and ensures long service life of it.
Principle: 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.
Constitution: Downhole motor is composed of five assemblies: by-pass valve, motor, anti-drop, cardan shaft and drive shaft.
The down-hole motor is a positive-displacement down-hole motor. It converts the high pressure fluid power of the mud into the mechanical energy of drill bit rotation. The motor is widely used in the drilling, making inclination, adjusting azimuth, coring, reaming, side tracking and work over for the directional wells, horizontal wells side tracked wells and straight wells of oilfields and coal mines. In addition, it is suitable for compound drilling and traversing and other special works.
