For chemical flooding，emulsification was one of the important mechanisms of enhanced oil recovery（EOR）. In the process of compound flooding，the emulsification could improve oil recovery significantly. The structure，properties and solubilization of surfactant-forming micelles in chemical flooding were introduced in this paper. The structure and properties of microemulsions and their applications in EOR were summarized. And the stability of emulsions and their effects in EOR were introduced. Finally，the development direction of compound flooding emulsification was summarized
