目前中国在陆相页岩油勘探开发过程中遇到了诸多难题和挑战。陆相页岩油储层孔隙结构复杂和渗流能力差极大地影响页岩油可动性，是制约陆相页岩油高效开发的突出问题。针对页岩开发面临的突出问题，简要介绍了国内外学者对页岩油储层孔隙结构表征和页岩油渗流规律研究方法和技术手段的现状、存在问题及今后的发展趋势。研究表明：多尺度、精细且连续表征是对陆相页岩油储层孔隙结构表征的关键；建立行业统一孔隙结构表征技术和分类评价标准是陆相页岩油有效开发的地质依据；多物理模型和实验手段相结合是陆相页岩油渗流表征的基础；加强数值模拟和物理模拟及室内实验结合是陆相页岩油渗流机理研究的主攻方向。这为突破陆相页岩油开发瓶颈提供了重要的指导思想，对实现陆相页岩油储层的高效开发具有重要意义。

At present, China has encountered many problems and challenges in the exploration and development of continental shale oil. The mobility of shale oil is greatly affected by complex pore structure and poor seepage capacity, and restricts the efficient development of continental shale oil. Therefore, In order to solve such prominent problem, the present situation, existing problems and future development trend of the research methods and technical means of shale oil reservoir pore structure and shale oil seepage law are briefly introduced. The results show that the characterization withe multi-scale, fine and continuous is the key to characterize the pore structure of continental shale oil reservoir. The establishment of the uniform pore structure characterization technology and the classification evaluation criteria is the geological basis for the effective development of continental shale oil. The combination of multi-physical model and experimental method is the basis of the seepage characterization of continental shale oil. Strengthening the combination of numerical simulation, physical simulation and laboratory experiments is the main direction of the study on the seepage mechanism of continental shale oil. It provides an important guideline for breaking the bottleneck of continental shale oil development and is of great significance to realize the efficient development of continental shale oil reservoirs.
