There are abundant shale oil resources in Jiyang Depression，and high-production industrial oil flows have been successively obtained in several wells such as Wells YYP1，FYP1，and BYP5 with peak production exceeding 100 t/d since 2019，which shows good prospects for shale oil reservoir exploration and development. Summarizing the geological characteristics of shale oil reservoirs in Jiyang Depression and analyzing their enrichment and high production regularities are of important guiding significance for the economic and effective development of shale oil reservoirs. Based on the review of shale oil reservoir exploration and development practices in Jiyang Depression，the main control factors for the enrichment and high production of shale oil reservoirs were recognized in this paper through systematic research on the petrographic characteristics，reservoir space，oil-bearing properties，and compressibility of shale oil reservoirs in Jiyang Depression. Research shows that shale oil resources in Jiyang Depression are abundant but scattered，characterized by high depths，high temperatures and pressure coefficients，and complex tectonics，petrography，ground stress，and fluid properties. The large thickness of hydrocarbon source rocks，high organic matter content，moderate thermal evolution，and the development of a carbonate-rich phase in the saline lake basin are the main factors for shale oil enrichment. The development of an inorganic pore-fissure network，high formation pressure coefficient，high brittle mineral content，good compressibility，hole expansion and energy enhancement by CO2，and multi-scale fracture network fracturing are the main factors for the high production of shale oil reservoirs in Jiyang Depression. The breakthrough of shale oil reservoirs in Jiyang Depression shows the broad prospect of exploration and development of shale oil reservoirs in continental rift basins，which is of great guiding and reference significance for the same type of reservoirs in China and abroad.
