摘要:

“2+3”采油技术以既能提高水驱油藏波及系数又能提高洗油效率为出发点而被提出,该技术综合了调剖和化学驱油的优点,从机理上完善了二次采油的不足,并减小了单一化学驱带来的高投资、高风险,为油田的有效开发提供了新的思路和方法。主要运用室内岩芯流动实验的方法,对“2+3”采油技术进行了调驱实验。为了深入分析和研究该技术的驱油效率,在相同实验条件下,把“2+3”采油技术的调驱实验结果分别同调剖实验结果和化学驱油实验结果进行对比。通过对比分析认为,“2+3”采油技术的调驱效率和提高原油采收率效果非常好。

关键词: 调剖, 驱油效率, 采收率, 采油技术, 高含水期

Abstract:

"2+3" oil recovery technology can be brought forward because it can enhance the sweep efficiency of water drive reservoir and the wash oil efficiency,the technology integrates the virtue of profile adjustment and chemical flooding.In mechanism,"2+3" oil recovery technology consummates the shortage of secondary oil recovery and reduces the high investment and the high risk which the single chemical flooding brings,which offers the new thought and method for the effective exploitation of oil field.In order to research the oil displacement efficiency and the EOR effect of "2+3" oil recovery technology,by the way of laboratory rock flow experiment,the profile adjustment efficiency,the oil displacement efficiency and the EOR effect of "2+3" oil recovery technology are researched respectively.After analyzing their experimental results synthetically,it is revealed that the EOR effect of "2+3" oil recovery technology is better.

Key words: profile adjustment, oil displacement efficiency, recovery ratio, oil recovery technology, high water cut stage
