The high viscosity of polymer solution can improve the mobility ratio between oil phase and aqueous phase. Therefore, it can expand sweep efficiency of displacing fluid. In the model of multi-polymer commixing flooding mechanism, each polymer flows in the porous media on its own ability, and the enhanced oil recovery process is resulted from the total concentration of all the polymers.
