Based on the study of the Newtonian flow I method, the formula of the non-Newtonian seepage flow I method is deduced. The pressure distribution formula and the average pressure calculation method of the non-Newtonian flow are given, and the Taylor series In combination with special functions, the power law exponent approaches 1, which simplifies the calculation of reservoir pressure when the concentration of polymer solution in the production well is very low.
