Hollow sucker rod is in order to effectively mining "high pour-point and high viscosity, high waxy" crude oil and the production of special sucker rod. In addition to the center of the hollow sucker rod hole to well into the heat transfer fluid (thermal oil, hot water, steam), chemical, or into the heating cable for viscosity melt wax, improve crude oil mobility; Can also be made of sand, salt solutions, slim-hole drilling, and layered oil production; Also can use its stiffness big, inherit the characteristics of the torque is used to drive the downhole screw pump.

Form a complete set of hollow sucker rod can be used for: (1) the hollow sucker rod injection heat carrier recovery device

2 hollow sucker rod electric heating device

(3) hollow sucker rod pump electric heating device

(4) secondary three layered water injection device

Tianjin fu petroleum machinery manufacturing co., LTD. Other product information:

Supply the hollow rod electric heating device abstract: purpose: with the percentage of heavy oil and high pour-point oil well drilling increases gradually, my company for the supply in the process of heavy oil and high pour-point oil mining hollow pumping rod doped rare device: the device for production in order to effectively mining high pour-point and high viscosity, high waxy crude oil and the development of special equipment. The device has the following main supply special hollow drive rod pump abstract: strength and reliability of the connection parts, reduce the sucker rod string is often broken rod, threaded, lu and other accidents.
