Hollow Sucker Rod Electric Heating Device in Oil Well

Hollow Sucker Rod Electric Heating Device for Heavy Viscosity OilA piece of device structure of hollow sucker rod electric heating device on the white background. Sketch map of hollow sucker rod electric heating device. Introduction In the high viscosity, pour point and wax content situations, the crude oil has the difficult of lifting and flowing into the pump, the sucker rod bears too heavy load to downstream. So, the common sucker rod cannot play a good performance in the late of oil exploitation. There is a new device which can solve these problems - hollow sucker rod electric heating device. Device structure The hollow rod electric heating device is main combine with three parts. Hollow sucker rod. Including the adapter connector, terminator, pony rod, polished rod, hanger connector and stuffing box. Heating cable. Power unit. Medium frequency power supply control cabinet. Classification The hollow sucker rod electric heating device can be divided into pumping unit well electric heating device, subsurface pump hollow sucker rod electric heating device and screw pump hollow sucker rod electric heating device.

Operating principle Cables pass through the hollow sucker rod and form a loop with the rod body. When the alternating current is connected, it will generate thermal energy through the internal skin effect. The thermal energy will heat continuously crude oil in the oil pipe. It can reduce the viscosity of the crude oil, prevent wax precipitation in the oil pipe and improve the fluidity of crude oil. Using this device can solve the problems in exploitation, it can also increase the production and improve the efficiency. The thermal energy generated by the internal skin effect is merely exist in the inner wall of the hollow sucker rod, the outer wall has no electric, and it can ensure the safety of operating. Tech
