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。

关 键 词:提高采收率  聚合物驱后  复合泡沫驱  气液比  室内实验

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 :1.
Keywords:enhanced oil recovery  polymer flooding  composite foam flooding  gas-liquid ratio  laboratory experiment
