摘要:

为了研究松辽盆地北部中浅层含油气系统演化及其对油气成藏与分布的控制作用,通过断层活动、油气生成排出和盖层封闭性形成史分析,研究了松辽盆地北部中浅层含油气系统演化及其特征,得到嫩江组末期、明水组末期和早第三系末期是松辽盆地北部中浅层含油气系统下延扩大的时期。造成扶杨、萨、葡、高和黑帝庙油层形成了“一源多层”和“一层多源”的油气成藏与分布特征,油气运聚成藏模式随含油气系统的演化而发生变化。

Abstract:

By analyzing the history of fault activity, generation and expulsion of oil and gas from source rocks and the sealing ability of caprocks, this work studied the evolution of petroleum systems and its control on the formation and distribution of oil and gas accumulations in the middle-shallow strata in northern Songliao basin. It is found that the end of Nenjiang formation, Mingshui formation and Eogene sedimentation were phases when the middle-shallow petroleum systems extended downward. As a result of these extensions, the F, Y, S, P, G and H oil layers are characterized by multi-oil layers having been charged by the same source bed or a single oil layer charged by multi-source beds. The mode of oil and gas migration and accumulation also change with the evolution of the petroleum systems.

Key words: northern Songliao basin, middle-shallow strata, petroleum systems, evolution, pool formation, distribution
