Abstract

On simulation of reservoir conditions in Daqing Oilfield, the effect of different method of multi-slug alternative injection, concentration gradually decreased injection, and concentration increasing injection on oil displacement efficiency are studied by laboratory experiment. The experimental results show that, under the condition of the same total amount of polymer, recovery percent of reserves of polymer flooding stage will increase with the increase of polymer concentration. The scheme which using the concentration gradually decreased method, the extent of enhancing recovery is maximum, polymer flooding recovery can reach 40.12%, and the ultimate recovery can reach 80.48%.
