摘要
为了充分利用丛式井距离较近的特点,试验应用一种“一拖二”互平衡式超长冲程节能举升系统。采用柔性钢丝绳替代部分抽油杆,通过电动机正、反转带动柔性钢丝绳上下运动,利用一上一下互平衡的方式实现了1台抽油机同时带2口井运转的目的。通过智能控制柜实现电动机柔性控制,配合井下超长冲程抽油泵,最大冲程可达50m,冲速1~12h-1连续可调。现场试验结果表明,平均单井节电率达32.6%,泵效提高25.1%,系统效率提高11.8%。
In order to make full use of the short distance of the cluster Wells,an energy saving lifting system of"one tow two"is applied in the test.The flexible steel wire rope is used to replace part of the sucker rod,and the flexible steel wire rope moves up and down through the positive and reverse of the motor,and the purpose of one pumping unit running with two Wells at the same time is realized by using the method of one top and one bottom mutual balance.The motor can be flexibly controlled through the intelligent control cabinet,and the maximum stroke can be up to 50 m with 1~12 h-1 continuous adjustable stroke.Field test results show that the average energy saving rate of single well is up to 32.6%,the pump efficiency is improved by 25.1%,and the system efficiency is improved by 11.8%.
