| Abstract: | There are two source rock systems of Shahai(J3sh )and Jiufutang(J3jf) Formations in upper Jurassic strata of Changbei anticline Zhangqiang depression. The abundance of organic matters is medium. Generally source rocks of J3sh are characterized by the saprohumic type.Geochemical analysis shows that lower source rocks of Shahai are in lower maturemarure. All the oil of different formations in Changbei is originated from the lower source rocks in Shahai Formation of upper Jurassic strata. |
