The fluid flow in fractured reservoir with fractures and fractures is studied. Three basic formulas of fractal permeability, porosity and seepage velocity are derived by introducing the differential relation of flow path length and unit cross-sectional area. The fractal pore media and fractal Difference between permeability and porosity expression in fractured media The pressure diffusion equation of single-phase fluid percolation in fractal reservoir is established, the solution of the relevant equation is given, and the typical curve for transient pressure analysis is plotted. Fractal reservoir and fracture fractal reservoir well test interpretation methods and steps.For the multidimensional anisotropic fractal medium, in Cartesian coordinates and cylindrical coordinate system is also given the corresponding seepage pressure diffusion equation for fractal reservoir exploration and development It is of great significance.
