摘　　要：重点考虑了混相过程中的相变、相间组份分配，对低界面张力情况下的油气渗曲线进行了修正，建立了一个一维三相全组份混相驱模型。应用研究中指出了多次接触混相的“前缘”和“后缘”特征，得到了不同驱替方式的采收率指标。模型的计算结果与实验数据吻合，所确定的混相参数已得到了应用。A three-phase one-dimensional fully compositional miscible flood model is presented inthis paper.Phase behavior andcomponents distribution between phases during miscible pro-cess is emphatically considered in the model.The oil-gas relative permeability curves at lowsurface tension situations is modified,The“front”and “rear”characteristics of multi-contactmiscibilitv are pointed out and the recovery indexes of different driving methods are estimat-ed.
