The two-dimensional (planar) geological model can not reflect the characteristics of vertical reservoirs and flooding changes of single sand body, especially the distribution of vertical residual oil and its variation in the plane. Therefore, the dominant permeability of single-body three-dimensional geological model is proposed Rate analysis method.According to the sedimentary microfacies of unit time in sedimentary time unit, the origin and spatial distribution of single sand body are determined, the formation process of single sand body is studied, and the internal structure of single sand body is established, the relationship between configuration and permeability and mathematical forecasting method The three-dimensional geological model of single sand body is established.On this basis, according to the research object to determine the value range and spatial distribution of the dominant permeability, through the analysis of the spatial flow path, the flooding process of the injector is studied to predict the flooding Degree and remaining oil distribution.
