摘要: 本文应用生物标记化合物(包括甾烷、萜烷、异戊二烯类烷烃和金属卟啉),碳同位素,正构烷烃以及红外光谱的某些基团特征等地球化学资料,将潜江凹陷潜江组不同产层的原油划分为潜四段、潜三段和潜一段三种类型。这三种原油类型的地球化学特征非常明显,颇有差异。通过原油与生油岩的对比,确定了三种原油类型的油源是来自本段的生油岩。

Abstract: Crude oils in the Qianjiang formation of Qianjiang depression are classified into three types on the basis of geochemical data pertaining to biological marker compounds (such as sterane, terpane, isoprenoids and metal porphrin), carbon isotope, n-alkane and some group characteristics. Each of the three types has its own distinct geochemical features.The source of these oils is determined through correlation of crude oil with the source rock.
