变频器对抽油机平衡度测试的影响

Converter influence to pumping unit balanced test

在经过现场大量测试的基础上,通过对变频器输入、输出端电参数的同步测量并录波,分析了变频器对游梁式抽油机平衡度测试准确性的影响。试验结果表明:使用变频器后,常规的测试方法不能准确地反映出抽油机的平衡情况。总结出使用变频器的抽油机平衡度测试的一般方法,对使用变频器抽油机的平衡度测试以及机采系统节能技术的研究具有一定的意义。

In the daily production of oil field,the balance of pumping unit is an important element to oilfield energy consumption.In conventional balanced test,we need measuring the electrical parameters of pumping unit.Along with the widely use of converter,the electrical parameters of pumping unit that using converter show very intensive particularity,only measuring the input of the converter can not accurately reflect the real balance of pumping unit.Based on lots of extensive test,analyzed the effect of pumping unit balanced test that using input and output electrical parameters of converter.At last,sums up the general method ofpumping unit balanced test.
