| Abstract: | The non-linear fractal theory was applied to fluid flow in heterogeneous reservoir. Through analyzing the fluid flow in real reservoir, the fractal dimension df and fractal index were introduced to describe the fractal characterization and reservoir heterogeneity, according to which the dynamic math model of dual permeability fractal reservoir was established. Consequently, the math model accurate solution was presented by using orthodox transform method. |
