Detail Introduction

Hollow Sucker Rod Electric Heating Device for Heavy Viscosity Oil

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 mainly combined with three parts.

·     . Including the adapter connector, terminator, pony rod, polished rod, hanger connector and stuffing box.

·     .

·     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.
