摘要
利用岩心压汞资料求出了孔隙结构分形维数；在此基础上，通过耦合孔隙结构分形维数建立了新的水驱油数学模型，采用历史拟合方法整理水驱油试验数据，以求得油水相对渗透率曲线，并与原有数学模型和计算方法进行了对比分析。
A new mathematical model for waterflooding experiment is constructed based on the mass fractal dimension obtained from mercury injection data. This model can be solved by finite difference method. Oil-water relative permeability is calculated by automatic history matching of waterflooding experiment data. A comparison is made between the relative permeability obtained from the proposed method in this paper and the results from JBN,and it has been shown that this method is feasible.
