摘要
本文分析了柴达木盆地东部地区新近系烃源岩的生物标志化合物的分布特征,探讨了烃源岩的有机质来源、沉积环境和成熟度。研究表明,新近系狮子沟组和上油砂山组烃源岩中生物标志化合物的分布特征大体相似,有机质为淡水-微咸水还原的沉积环境,母质来源以高等植物为主,也有低等水生生物的贡献。
This paper describes the distribution characteristics of biomarkers in Neogene source rocks at Eastern area,QaidamBasin and investigates the origin,depositional environment and maturity of organic matter in source rocks.Results show that thedistribution characteristics of biomarkers in Neogene source rocks at Shizigou Formation and Shangyoushashan Formation is generallysimilar.The source rocks is developed in reducing fresh-brackish water sedimentary environment and the parent source is from thehigher terrestrial plants and the lower aquatic lives.
