摘　　要：储层的微观孔隙结构直接影响着储层的储集与渗流能力,因此,研究储层的微观孔隙结构特征有利于对储层进行合理的分类评价,进而查明储层的分布规律,提高油气产能及油气采收率。在调研大量相关文献的基础上,对储层微观孔隙结构成因、实验方法、理论研究进展和综合评价等方面进行了系统的总结和阐述,并对国内储层微观孔隙结构研究中存在的主要问题进行了分析,指出国内微观孔隙结构的研究主要以传统的研究方法为主,存在与国内地质实际结合不够及定量化研究不足等问题。Reservoir microscopic pore structure directly affects the reservoir storage and permeability, so the research on reservoir microscopic pore structure characteristics can help to carry out reasonable classification evaluation of reservoir, and find out reservoir distribution law, improve the productivity and recovery ratio of oil and gas. Based on a large number of relevant literatures, this paper summarized and expounded the origin, test methods, theory research progress and comprehensive evaluation of reservoir microscopic pore structure, analyzed the main existing problems in the research of domestic reservoir microscopic pore structure, and pointed out that the research of the domestic micro structure is mainly based on traditional methods, having the problem of insufficient combination with domestic actual geological condition and lack of quantitative research.
