Tight oil has a broad prospect of exploration and development and has become an important replacement resource for conventional oil resources. The enrichment and recoverability of tight oil are closely related to the reservoir structure. The reservoir structure not only determines the occurrence mode of tight oil, but also the key factor affecting the economic development of tight oil. The study of shale reservoir structure has always been the core work of tight oil resources evaluation, and it is also the research hotspot and frontier in the field of oil and gas geology. Based on previous studies, this paper briefly summarizes the characteristics of tight oil reservoirs.
