Abstract

In the middle and late stage of water flooding reservoir, the existence of high permeability channel of water flooding affects water flooding efficiency and thus affects oil recovery. Nitrogen foam flooding is one of the important ways to improve oil recovery after water flooding, but foam flooding only emphasizes the ability of foam to expand sweep volume, but recent studies show that it also needs to enhance its oil washing ability. To solve this problem, reservoir numerical simulation software CMG was used to simulate nitrogen foam flooding. The results show that the effect of injecting multiple nitrogen foam slug and surfactant slug alternately is better than that of injecting only nitrogen foam, and the effect of increasing oil and reducing water cut becomes better with the increase of nitrogen foam, surfactant slug size and gas liquid ratio.
