【 摘 要 】

In the north of Songliao basin, some high CO2 gas reservoirs have been found while great breakthroughs have been made in hydrocarbon natural gas. Based on the analysis of the reservoir characteristics of CO2 gas reservoirs in Xudong area, this paper clarifies that the Yingcheng formation CO2 is inorganic gas, volcanic rock is the main reservoir, and establishes the differential accumulation model of CO2 gas reservoirs in the study area, which can also guide further research and exploration.
