摘要：In this study, we analyzed the characteristics of the classⅡreservoirs and the application of the polymer flooding in Daqing oil field, and also discussed the effects of polymer flooding parameters on reservoir properties and displacement results by numerical simulation. Based on the conceptual model of sandstone reservoirs, we studied the effects of the concentration, viscosity, relative molecular mass of polymer, and the injection rate on the recovery of polymer flooding by single factor analysis. We found that the variation of these factors had obviously effects on the results of polymer flooding to a certain limit. In the process of discussion, we treated the parameters of polymer by linear regression to analyze the results of polymer flooding, which can provide some guidance for reservoir development.
