摘要/Abstract

摘要： 使用色谱和色谱-质谱技术研究了辽河西部凹陷的原油和油砂的饱和烃,鉴定出多种生物标记化合物,特别是鉴定出了25-降藿烷系列和一个待确认的新的化合物,这些化合物对指示原油的生物降解作用具有指纹意义.严重的生物降解作用可破坏原油的正常甾烷,并使正常藿烷向25-降藿烷转化.“稠油”中25-降藿烷的存在,说明它们形成的一个重要方式是生物降解作用.

Abstract: The saturated hydrocarbon of crude oil in the Western Depression,Liaohe Basin have been analyzed By computerized GC-MS.The hopanes,regular steranes,diasteranes,specifically,25-norhopanes were identified.Heavy biodegradation results in destruction of regular steranes and transformation of regular hopanes to 25-norhopanes.Diasteranes and 25-norhopanes survive heavy biodegradation and they can be used as source fingerprints for biodegraded crudes.The existence of the diasteranes and 25-norhopanes in the "thick oil" shows that the biodegradation plays important part in origin of the "thick oil".
