大泵排液采油工艺是注水开发油田稳产挖潜的重要手段。文章阐述了以抽油方式为主的非均质注水开发油田,在中高含水开采阶段产液量、产油量与含水量的变化关系;在采用大泵排液采油、含水不断上升的情况下,对提高采液量、稳定产油量进行了分析;总结了胜利油田采用大泵稳产的经验和教训,以及对今后如何搞好大泵排液采油、提高大系稳产效果提出了改进意见。
Big pump draining oil recovery process is an important means of taping and developing oil field steady potential tapping potential. This paper describes the development of heterogeneous waterflooding oilfields with the pumping method as the main mode of production. During the middle and high water cut stage, the relationship between liquid production, oil production and water content is discussed. When large pumps are used to drain oil and water is continuously rising , Analyzed the increase of liquid production and stable oil production; summed up the experience and lessons learned from using large pump to stabilize production in Shengli Oilfield; and put forward some suggestions on how to improve the efficiency of large-scale drainage and oil recovery in the future.
