换大泵是抽油机井的主要提液措施。但是随着油田含水的上升,单井措施增油量大幅度下降,大部分井出现了“增液不增油”、“降液降油”等现象。因此,有必要对高含水期的有效提液进行研究。本文通过对我厂两年来采取提液措施的116口抽油机井的增产情况进行统计分析,利用数据统计和盈亏平衡分析方法,从措施效果和效益两个方面进行论证,取得了一些认识,为提液措施的确定提供借鉴。
Change the pump is pumping the main wells pumping solution. However, with the increase of water content in the oilfield, the amount of oil increased by single-well measures dropped sharply. Most of the wells experienced such phenomena as increasing fluid without increasing oil concentration and decreasing fluid with decreasing oil mass. Therefore, it is necessary to study the effective extraction of water in high water cut period. Based on the statistical analysis of the increase of 116 pumping wells taken by our factory in the past two years, this paper uses data statistics and breakeven analysis methods to demonstrate the effectiveness and benefits of measures, and obtains some understandings as Liquid extraction measures to determine the reference.
