摘要: 塔里木盆地塔北隆起轮西地区重油具有低饱和烃(或低饱和烃与芳香烃比值) 和高含蜡、高含硫、高胶质、沥青质的特征, 说明该地区原油经历了大量的轻烃散失和降解过程。通过对该区原油生物标志物特征分析和储集层沥青研究, 认为该地区原油主要为中下寒武统和中下奥陶统烃源岩的混源油。同时, 从烃源岩发育及油气充注的时期分析, 也可以得出中下寒武统和中下奥陶统烃源岩是轮西奥陶系潜山油藏的主要油源的认识。

Abstract: The heavy oil in the western Lunnan area is characterized by low saturated hydrocarbon or low saturated hydrocarbon to aromatic hydrocarbon ratio, high content of wax and high colloid and asphaltene, showing that the oil experienced diffusion of light hydrocarbons and degradation of microorganism. It is concluded that the oil in this area is the mixed oil derived from Middle-Lower Cambrian and Middle-Lower Ordovician source rocks based on the oil biomarkers and reservoir bitumen analysis. According to the source rock development and hydrocarbon filling periods, it could also get the same conclusion that the oil in Ordovician buried hill reservoir is filled by hydrocarbons generated mainly from Middle-Lower Cambrian and Middle-Lower Ordovician source rocks.

Key words: source rock, biomarker, reservoir bitumen, hydrocarbon source, Tabei uplift
