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. Based on influence equations, production target prediction models are built usingHall curve theory, relative permeability curve, relations of water saturation and relativepermeability and material balance equation. Parameters of models are calculated by the way ofcomputer program and so that a simple, fast way have been gained to predict production targetof polymer subsequent flooding.
