摘要

通过对比聚驱后聚表二元复合泡沫驱四种不同气液比(1:2、1:1、2:1、3:1)的实验结果,优选出最优的气液比,并对泡沫驱油机理进行进一步的阐述,为现场矿场试验提供理论依据和参考。实验结果表明,在水驱和聚驱效果相似的条件下,聚驱后二元复合泡沫驱四种不同气液比方案采出程度的大小关系是3:1 < 1:2 < 2:1 < 1:1,最优气液比为1:1。

Abstract

The best gas-liquid ratio among the experimental results of four different gas-liquid ratio (1:2, 1:1, 2:1, 3:1) is picked out after polymer surface foam compound flooding in this paper, and further explanation of elaborated mechanism is made, providing a theoretical basis and reference for oilfield test. The results show that the best gas-liquid ratio of compound foam flooding system is 1:l.
