摘要
对白音查平凹陷生物降解稠油物性及地化特征进行研究，认为该凹陷稠油宏观上具有密度、粘度、凝固点高，饱和烃含量低，饱和烃与芳烃比值小的特征；微观上烷烃色谱及生物标志物表明稠油为两期混合油，成熟度属低－较成熟油的信息。通过同位素技术恢复了达6井稠油密度后，以生物标志物及物性特征将该凹陷稠油划分为三级降解油，为了解该区含油气远景和地质勘探部署提供了可靠依据。
According to physical property and geochemical characteristics of biodegradation viscous crude oil in Baiyinchagan Depression, it has been indicated that macroscopie characteristics of viscous crude oil is higher density, higher viscosity, higher soildifying point, lower saturation hydrocarbon content and small value of ratio of saturated hydrocarbon to arcomatic hydrocarbon; in microcosmic saturated hydrocarbon chromatogrom and biomarkers shows that viscous crude oil is two stages miscible oil, and maturity is from low to maturer. By the use of stable isotope technology, density of viscous crude oil of well Da 6 has been resumed. According to characteristics of biomarkers and physical property of viscous crude oil, it could be divided into three classes. This offers reliable basis for understanding hydrocarbon potential and making exploration decisions in this area.
