一种新型空心抽油杆中频感应电加热技术

A new technique of medium-frequency induction electric heating for hollow pumping rod

稠油和高凝油开采过程中的降粘和降凝问题一直是国内外石油开采业所关心的问题之一。现文提出一种新型空心抽油杆中频感应电加热技术 ,有效地克服了原空心抽油杆单相工频电加热技术在应用中存在的加热效率低、三相电网不平衡和电气设备有效容量利用率低等问题 。

The problems caused by high viscous and solidifying oil is concerned by all of the oil corporations in the world.This paper presents a new technique of medium frequency induction electric heating for hollow pumping rod,which is applied to solve the problems, such as low heating efficiency, unbalanced three phase power, poor utilization ratio of rated capability of the electric apparatuses employed at each oil well etc., existed in single phase power heating technique for hollow pumping rod. The practical test results are reported at the end of the paper.
