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.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
