Abstract


Combining the oretical analysis and actual production data statistics, the paper found that concentration of polymer solution at a point in the stratum had exponential relation with the distance away from injectors. Based on viscosity model considering shear degradation and polymer concentration, a non-Newtonian power-law fluid well test interpretation model is built. Then well test interpretation chart of polymer flooding is proposed by numerically resolving the new model. Example analysis shows that the polymer flooding well test interpretation method and chartprovide a theoretical and technical support for explaining reasonably formation parameters under conditions of polymer flooding and quantitatively evaluating the effects of polymer flooding.
