Anti Drop Downhole Motors

Product Description

At present, our production which is downhole motor with a anti-drop has applied the national patent. The anti-drop screw drilling downhole motor produced by our company is convenient to use. Besides, its structure is simple. Screw drilling Downhole Motors with anti-drop may prevent droping accident, that's the reason why anti-drop downhole motors improve drilling efficiency.


Downhole Motors with a Anti-drop Rotor

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.
