摘要 分析了甾烷类“分子化石”(生物标志化合物)在塔里木盆地某些特定地质年代岩石中的分布特征并藉此为“指纹”进行油源对比.分子化石的分布受成熟作用、运移作用、相分馏作用及生物降解作用等因素的综合影响,并不是任何一个与生源环境有关的分子化石参数都可作为油源对比的指纹.甲藻甾烷(C_(30))、4-甲基-24-乙基胆甾烷(C_(30))及其芳构化甾烷、24-降胆甾烷(C_(26))及C_(28)甾烷等来源于沟鞭藻和硅藻等生物的分子化石在塔里木盆地寒武系和奥陶系岩石抽提物中普遍存在,并且在不同层系中的分布具有明显的差异性。除塔东2井产自寒武系地层中的重油等少数几个油样与寒武系抽提物有可比性之外,在塔中、塔北隆起上的海相原油中,这些化合物的相对含量与上奥陶统抽提物之间表现出惊人的相似性,这意味着中、上奥陶统生油岩可能是这些海相原油的主要生源。
