摘要
By analyzing the difference of crude oil maturity,preferred direction of hydrocarbon migration,distribution of hydrocarbon,shielded effect of trap on hydrocarbon migration,and geochemical characteristics of source rocks,and by combining with chemistry kinetic method,the oil-source of Changchunling anticline in the northern Songliao Basin,and the resource of its oil-source area were studied.The results show that the crude oil maturity of Changchunling anticline is similar to that of Wangfu Depression,but significantly lower than that of Sanzhao Depression and Chaoyanggou terrace.Changchunling anticline is on the preferred direction of hydrocarbon migration from Wangfu Depression.The distribution of crude oil is around Wangfu Depression on level.Chaoyanggou terrace shields the hydrocarbon migration from Sanzhao Depression to Changchunling anticline. The crude oil of Changchunling anticline comes mainly from Wangfu Depression.The source rocks of Qingshankou Formation in Wangfu Depression are high abundance of organic matter,good type,but low maturity.
