Abstract	A mathematical model of the polymer solution flow in porous media is established with the different concentration distribution. The polymer solution is treated as the power law non-Newtonian fluid with its power law index depended on the concentration of the solution. The finite element method is used to solve the problem by considering the effects of the concentration distributions and the different boundary conditions on the process of pressure conduction. The wellbore pressure and pressure distribution have been determined. For the different case, the type curve of pressure and its derivate have been analyzed. Some in situ test data are analyzed to verify the new model by using the type curve matching method. The results show that the concentration distribution of the polymer solution in the porous media is clearly reflected by the power law indexes changed along the distance. The characteristic parameters of the porous media and the polymer solution distribution can be determined by analyzing the in situ test data. The new model has been extended to more complicated boundary cases.
