Abstract

By comparing the oil displacement experiment of Huading I and Haibo BI polymer surfactant based on the actual the situation of reservoir in Daqing oil field in this paper, the displacement efficiency for two kinds of polymer surfactant in different concentration and different slug were compared. In the optimized concentration experiments, there was an inflection point of increasing range for the degree of reserve recovery when concentration of Huading I and Haibo BI polymer surfactant is 1000mg/l. The increasing of recovery efficiency slow down gradually with the increasing of concentration; In the optimized slug experiments, the increasing range of the oil recovery was the largest when the injection of Huading I and Haibo BI polymer surfactant was 1 multiple of pore volume injected. Considering concentration and degree of reserve recovery, optimized concentration of Huading I and Haibo BI was 1000mg/l and their optimized slug were 1 multiple of pore volume injected.
