摘　　要：微乳液驱和泡沫驱是强化采油领域中的两个重要技术,可以分别提高驱油过程的微观和宏观采收率。通过综述两个技术在国内外的发展历史和研究进展,阐明了其优势和局限性,并引出结合两者优势的新型采油技术:微乳液泡沫驱,又称为低张力泡沫驱。虽然此新型技术可以同时提高微观和宏观采收率,但是在实际应用中,仍然面临理论和应用上的双重挑战,如表面活性剂有效窗口狭窄、注入工艺复杂、流体流动模型不完善等。结合文献调研,针对以上问题提出了一系列研究建议,如采用"专剂专用"原则开发微乳液泡沫剂,利用数值模拟来优化注入工艺等。Microemulsion flooding and foam flooding are two important technologies in enhanced oil recovery(EOR),which can improve microscopic and macroscopic oil recovery efficiency,respectively.The advantages and limitations of two technologies are illustrated through the review of their development and research progress for introducing microemulsion-foam flooding,also known as low-tension-foam flooding.This novel EOR technology combines the advantages of the above technologies,and can enhance both microscopic and macroscopic oil recovery efficiency.However,there are still theoretical and practical challenges,such as narrow effective window of surfactant,complex injection strategy,and incomplete hydrodynamic model in respect of application.By reviewing literature,systematic research suggestions are proposed for above challenges,such as“one formulation one case”principle for designing surfactant formulation,optimization of injection strategy by numerical simulation,etc.
