Microemulsion, because of its excellent interfacial tension reduction and solubilization properties, has wide range of applications in the petroleum industry, especially in improved oil recovery (IOR). Herein, the concept, types and formation mechanism of microemulsion were primarily introduced. Then, the preparation and characterization methods were illustrated. Additionally, several effect factors were elaborated specifically based on the composition of microemulsion. Finally, the application of microemulsion in IOR was addressed, including IOR mechanism analysis based on sweep efficiency and displacement efficiency, injection method (microemulsion flooding, in-situ microemulsion formation) and field tests. Furthermore, the current challenges and prospects of microemulsion on IOR were analyzed.
微乳液因其出色的降低界面张力和增溶性能，在石油工业中有着广泛的应用，尤其是在提高采收率（IOR）方面。本文首先介绍了微乳液的概念、类型和形成机理。然后，阐述了其制备和表征方法。此外，还基于微乳液的组成具体阐述了几个影响因素。最后，探讨了微乳液在提高采收率方面的应用，包括基于波及效率和驱替效率的提高采收率机理分析、注入方法（微乳液驱油、原位形成微乳液）和现场试验。此外，还分析了微乳液在提高采收率方面当前面临的挑战和前景。
