Abstract:

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.

Key words: continental shale oil reservoir, pore structure, seepage law, existing problem, research progress and prospect
