摘要：

黄河南地区的油气主要来自邻近的前梨园、葛岗集和崮阳3个洼陷的沙河街组三段和四段生油岩.流体势分析结果表明:白庙和桥口地区的主要供油气区为前梨园洼陷和葛岗集洼陷;徐集地区和马厂地区的油气主要来自葛岗集洼陷;而崮阳洼陷的油气则主要供给三春集地区.西掉断层致使油气呈阶梯式运移,除白庙地区外,输导层每穿越一条西倾断层,油气的层位就可能更新一次,每穿越一条东掉断层,油气的层位就可能变老一次.由于受断层和油源的影响,黄河南地区的油气田紧临生油洼陷呈环状分布,油气多富集于继承性发育的披覆构造中的断块圈闭内.

Abstract:

Hydrocarbon in South Yellow River Region are derived from Sha 3～4 member source rocks of the neighbouring front Liyuan,Gegangji and Guyang Sags.The analysis result of fluid potential suggests that the main hydrocarbon supplying areas of Baimiao and Qiaokou areas are the front Liyuan and Gegangji Sags;that of Xuji and Machang areas is Gegangji Sag;that of Sanchunji area is Guyang Sag.Westward dounthrown faults resulted in hydrocarbon step migration.Hydrocarbon bearing horizons would get younger each time when transport layer passed through west tilted fault but things would be opposite when the transport layer passed through every eastward downthroun fault,excepting Baimiao area.Oil and gas fields in the South Yellow River Region are distributed annularly near oil generation sag,oil and gas are enriched in the fault block traps of inherited drape structures.

Key words: oil source, migration, accumulation, distribution regularity
