冲积扇是中国特高含水油田最主要的沉积相类型，其水动力条件复杂、储层非均质性强，研究程度较低，具有较大开发潜力。冲积扇储层提高采收率、挖掘剩余油是特高含水油田效益稳产的关键问题之一。综合分析了近几十年国内外学者的研究成果，探讨了冲积扇储层剩余油研究进展及发展方向，认为冲积扇宏微观储层特征研究逐渐精细化、精准化，剩余油研究方法正在向定量化、可视化发展，而关于剩余油的形成及动用机理的研究仍处于探索阶段。结合上述国内外研究现状的综合评述，指出未来冲积扇储层剩余油的研究应重点关注3个问题： 1）宏微观储层及宏微观剩余油的关系研究； 2）剩余油的动用机理的探讨及应用； 3）多学科深度融合的研究方法创新。

Alluvial fan is the most important sedimentary facies types in oilfields with ultra-high water cut in China, which has complex hydrodynamic conditions, strong reservoir heterogeneity, low research degree and high development potential. Enhancing oil recovery and tapping remaining oil in alluvial fan reservoir is one of the key problems for stable production in oilfields with ultra-high water cut. In this paper, the research achievements of scholars at home and abroad in recent decades are comprehensively analyzed, and the research progress and development direction of remaining oil in alluvial fan reservoir are discussed. It is considered that the study of macro and micro reservoir characteristics of alluvial fan is more and more precise, the research methods of remaining oil are developing towards quantification and visualization. However, the study on the formation and mobilization mechanism of the remaining oil is still in the exploratory stage. Based on the above review, we conclude that three issues in the study of remaining oil in alluvial fan reservoir should be focused. The first is the relationship between macro-micro reservoir and macro-micro remaining oil, the second is the exploration and application of remaining oil production mechanism, and the third is the research method innovation of deep fusion of multi subjects.
