The Realization And Application Of Numerical Simulation With High-expansion Water Flooding In Strong Edge-and-bottom Aquifer Reservoir

Because of the special geographical environment of abundant energy edge-bottom water,the reservoir is washed many times.Compared with conventional reservoir,high-expansion water flooding relative permeability curve is particularly important.It is necessary to develop a new numerical simulation method.To solve these problems,the following jobs are processed.Firstly,the physical simulation experiment method is used to finish artificial core displacement experiments in this article.And the characteristics of relative permeability curves are analyzed after the physical experiments.Then the high-expansion water flooding relative permeability curves are applied to study different application methods in numerical simulation.The applicability of the different implementation methods are summarized.Finally,the numerical simulation method is applied in actual strong edge bottom water reservoir to contrast conventional displacement relative permeability curve and high-expansion water flooding permeability curve.A set of suitable method is summed up for strong edge bottom water reservoir to enhance oil recovery.This paper breaks through the limitation of the normal numerical simulation method.Relative permeability curves in different high displacement ratios using for numerical simulation method is realized,which is significant to make development plan better for the strong edge-and-bottom aquifer reservoir.
