The cor relation between crude oil and hydrocarbon source rockswas also researched by combined characteristics of biomarkers. It is shown that there are six types of the crude oils in Nanpu sag, which have different compositional characteristics. The type I oil occurs in the Nm and Ng in L iuzan, Gaoshangpu and Laoyemiao Oilfield. The type II oil occurs in Ed of Gaoshangpu, Laoyemiao and BeipuOilfield. The type IIIoil occurs in L iuzan Oilfield andGaoshangpuOilfield in the north ofGaoliu fault. The type IV oil occurs in Ed reservoir. And the typeV andV I oil occur in Ordovician reservoi
