摘要
Based on the study of basin formation and evolution controlled by foundational fault and activity strength of basin-controlling fault in different period,the different basin groups are divided,including Lujiapu,Kailu and Zhangwu basin groups in Songnan Area.Organic geochemistry measurements and analyses are conducted on dark-colored mudstones and carbonaceous mudstones in Jiufotang and Shahai Formation hydrocarbon source rocks.The results indicate that the hydrocarbon generation potential of Lujiapu basin group,which has the strongest potential of hydrocarbon generation,is better than that of Kailu and Zhangwu basin group.In vertical profile,the quality of hydrocarbon generation of Jiufotang Formation is better than that of Shahai Formation.This trend is mainly controlled by different activity strength and time of foundational fault and basin-controlling fault and it is also affected by the impact of depth.Therefore,in next exploration in Songnan Area,the key point of study is the hydrocarbon source rock of Jiufotang Formation,but in some rift basins,the hydrocarbon source rock of Shahai Formation is the major object of study.
