Abstract: In this paper, the mathematical expression of the effective viscosity of viscoelastic fluid was derived, and the mathematical expressions of the fractal porosity and fractal permeability of porous media were given. The mathematic model of the flow of the viscoelastic fluid through the fractal porous media was established and the numerical solution of the mathematical model mentioned above was obtained using the finite difference method. In addition, the Lagrange interpolation method of the calculating rate of flow under the condition of stable flow and different pressure was presented. The practical calculation of the production of five wells which were flooded by ASP in the No. 4 Oil Recovery Factory of Daqing Oilfield was conducted. The calculation results show that the mathematical model of the flow of the viscoelastic fluid through the fractal porous media and the method of numerical calculation in this paper are correct.
