摘要：

石油的主要元素为碳和氢,其次为氮、硫、氧。研究这些元素的稳定同位素,对于认识石油的形成与演化有重要意义。这方面的研究报道已比较多。本文对不同沉积环境下形成的原油及其饱和烃组分和芳烃组分的δ13C、δ34S、δD 进行了研究,分析工作是在美国联邦地质调查所完成的。

Abstract:

The enrichments of δ13C,δ34S and δD in crude oils gathered in various places,both in China and abroad,are studied and reported in this paper.For oils formed in salt lakes,their δ13C ranges from-24.70‰ to-28.30‰,averaging-25.86‰,δ34S from 12.30‰ to 1.00‰,averaging 7.57‰,and δDranges from-148‰ to-98‰,averaging-135.40‰.For oils formed in freshto brackish lakes,δ13C ranges from-24.61‰ to-29.60‰,averaging-27.49‰,δ34S from 17.02‰ to 4.51‰,averaging 10.48‰,and δD from-161‰ to-137‰,averaging-146.89‰.The enrichments of δ13C,δ34S and δD from salt lake oils and marine oils have some similarities.They are probably reflecting the primary types of organic matter as well as depositional environments,and may be influenced in some extent by the maturity of crude oil.
