Fluid flow in porous and fractured fractal reservoirs is studied in the paper. The basic formulae of
seepage velocity, permeability and porosity in both porous and fractured fractal media are developed.
The pressure diffusion equation of slightly compressible fluid in fractal reservoirs is derived. The analytical
solutions of the transient pressure are given for the line-source well and the well with well-bore
storage and skin factor. The typical curves of pressure and the derivative of pressure are established,
along with the interpretation of the well-testing method via type-curve matching. In addition, 3-D pressure
diffusion equations for anisotropic fractal media are given in both Cartesian coordinates and Cylindrical
coordinates.
