摘要
Abstract
Through dissecting Qingtujing shallow oil reservoir and combining this with regional studies, the condition of oil-gas accumulation in Jinchang depression of Chaoshui is analyzed systematically, from this the authors suggest that the main reason that Qingtujing shallow oil reservoir could be preserved is due to anticline controlling, fault covering up and lithologic sealing, and that oil pools are small is because of severe destruction and bad reservoir physical property as well as lack of good collocation between trap condition and oil source condition. Regional study shows that the source-reservoir-sealing conditions lie the trend from bad to good from depression edge to depocenter, and trap condition is good. Finally, authors suggest that exploration in future should be done around the depocenter and early structure (e.g. Jinchuan structure) should be chosen to drill, and searching medium-small size oil-gas reservoirs should be taken as the key in basin exploration.关键词
