调速(低速)技术在抽油机上的应用分析

Application of Low Speed-adjustable Technology for the Beam Pumping Unit

针对目前低产液量井抽油机上应用种类繁杂的调速(低速)技术的现状,我们选取了具有代表性的电磁调速电机、变频器、16极永磁电机,在抽油机井场进行了节电效果的对比测试。根据测试结果和多年对各种调速(低速)技术节电效果的试验情况,分析了目前抽油机上应用的8种调速(低速)技术的不同特点,最后得出了如何在抽油机上优选调速(低速)技术的结论。

Based on the problems in the application of various motor timing technique for low liquid-output wells,the power saving contrasting test has been carried out in beam pumping field with electromagnetic speed adjustment motor,frequency converter and sixteen-pole permanent magnet synchronous motor.According to the testing result and the experience achieved in power saving test of timing technique for several years,the character of eight kinds of timing technique that being applied on beam pumping unit is inves...
