摘　　要：为了通过宏观控制图准确描述潜油电泵井泵排量的合理度,消除实际抽汲时流体中含自由气或含水的影响,提出根据油层产出流体的性质对泵的特性曲线进行黏度修正和含气修正,并根据修正后的电潜泵特性曲线确定出符合实际流体条件的泵排量上下限,进而确定出泵排量合理度的方法。通过对比分析证明,考虑特性曲线修正后的电潜泵宏观评价结果更加符合油井的实际工况,对指导油井日常管理具有重要意义。In order to determine pump displacement rationalization by Mocro-control diagram with eliminating effect of free gas and produced water,viscosity and gas revisions are presented according to produced fluid from formation,then the upper and lower limit of ESP displacement fit for real fluid condition are derived from ESP characteristic curve,at the end,pump displacement rationalization is determined.Furthermore,in terms of comparing ESP macro-evaluation result considering characteristic curve revision and that without,it has been proved that the former method conforms to the real situation much better than the latter,therefore,this method will be a good guide in ESP management at the oilfield.
