摘　　要：驱替剂的作用是使残余凝胶体在岩石孔道内就地混凝,可通过混凝剂筛选实验研制出来;混凝剂的注入参数需要优化,可通过岩心模拟评价实验来完成。通过实验可以得出以下2条结论:第一,区块的调驱液波及系数和洗油效率可以得到改善,从而使得采收率进一步提高。第二,铁类溶液是作为混凝剂的最佳配方。The function of displacement agent is to coagulate residual gel in situ in rock pore,which can be developed by coagulant screening experiment. The injection parameters of coagulant need to be optimized,which can be accomplished by core simulation evaluation experiment. The following two conclusions can be drawn from the experiment:Firstly,sweep coefficient and oil washing efficiency of profile control and flooding fluid can be improved,so that oil recovery can be further improved. Secondly,iron solution is the best formulation as coagulant.
