摘要：
During the chemical flooding, the surfactant and the alkali play an emulsifying role. The emulsification can not only improve the displacement efficiency, but also expand the swept volume by the mechanism of emulsifying trapping. We select some chemical flooding systems including different kinds of surfactants, alkali/alkali-free and different emulsion degrees to make the comparative experiment and draw the conclusion that it is an effective way to enhance the recovery by increasing the emulsion stability without having to pursue the ultra-low interfacial tension.
