Shandong Dongyuan Petroleum Equipment Co., Ltd

This is Shandong Dongyuan Petroleum Equipment Co., ltd that is established in 1998.It is mainly produced downhole motors with big torque, high effective, wide flow rate range, running stable, and long using time.The downhole motor covering a range of diameters from 45~286mm falls into many varieties such as the single-bent, double-bent, steerable, deephole high temperature, and hollow distributary type, etc,
Shandong Dongyuan Petroleum Equipment Co., Ltd. established in 1998 in China is a manufacturer of downhole mud motor which is usually used together with cone bits, diamond bits and so on in drilling operation, such as directional and vertical drilling, horizontal drilling, correcting deviation, coring, reaming, sidetracking, etc.
We can supply the downhole motors(2-3/8"OD to 11 1/4"OD) with different types and specifications. All the products have a wide range, good quality, reasonable prices and stylish designs, our products are extensively used in petroleum drilling engineering and other industries.
The principle of our downhole 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.
