Tight oil is abundant worldwide, including in China, and has high development potential, and is an important source of energy for the replacement of conventional oil resources. However, tight oil reservoirs have unique resource formation, resource characteristics, and accumulation conditions that are different from conventional oil and gas resources. The key to the successful development of tight oil is the generating conditions and reservoir conditions of tight oil reservoir conditions. In this paper, based on previous studies in China, the geological characteristics and enrichment characteristics of tight oil reservoirs are systematically summarized from the generating conditions and reservoir conditions, and the value range of evaluation indexes for the sweet core area of tight oil in China is defined. This paper has a certain reference value for the formation and distribution of tight oil and resource potential evaluation.
