合理调小冲次,提高抽油机井的系统效率

Reducing Frequency of Stroke Reasonably to Improve System Efficiency of Pumping Well

针对中原油田抽油机井泵效和系统效率普遍较低、油井维护工作量大的问题 ,参考江苏、胜利等油田优化参数、提高系统效率的做法 ,结合中原油田系统测试情况 ,进行了深入细致的综合分析对比后 ,认为近年来抽油机井工作条件普遍发生了变化 ,有必要科学合理地调小抽油机井的冲次 ,并给出了实施方法 ,目的是有效地提高抽油机井的系统效率 ,节能降耗 ,同时延长抽油杆、油管的使用寿命 ,延长抽油机井的免修期 ,达到降本增效的效果。

The pump efficiency and system efficiency of Zhongyuan Oil-field are widely lower,workload of well-maintenance is heavy.To settle this problem,we refer to the methods like optimizing well-production parameters to improve system efficiency in Jiangsu and Shengli Oilfield,and combine these methods with system efficiency measure instances in our Zhongyuan Oilfield,go along careful contrast and analysis,and consider that with the continuous changing of working situation of pumping wells these years,it is necessary to reduce the stroke frequency of pumping wells reasonably,further more,we give out a proposal method to reduce the frequency of stroke practically.Our purpose is to improve the system efficiency of pumping wells,save energy costs,prolong the use time of sucker rod and tubing string and so on,and increase our benefit ultimately.
