The priorities are the diversification characteristics of each targetin the subsequent water flooding. According to diversification characteristics of these targets,the paper studies how the heterogeneousness, water flooded condition, interconnectingcondition of zone;key measures injector parameters affect these targets from polymer floodingmechanism.
