| 摘 要： | 详细研究了吉林伊通地堑下第三系生油岩和原油中的芳烃生物标志物，包括常规的多环芳烃，以及丰富的来源于高等植物的芳香二萜和芳构化的五环三萜。目前，原油中芳构化五环三萜类生物类生物标志物国内外均尚报道极少。还详细讨论了利用原油中最新发现的芳构化五环三萜在解决本区生物输入，油源对比以及石油成因等方面的重要意义。

| Abstract: | Including aromatrc di-, sester- and triterpenoid hydrocarbons with retene or octahydrochrysene or polyaromatic oleanane as the predominant species, the polycyclic aromatic hydrocarbons of the crude oils and related source rocks from the Yitong graben, Jilin, northeastem China, have been charaterized in detail. On the basis of the distribution of polycyclic aromatizic biomarkrs, the biological inPut and oil/source Gorrelation of the Ytong graben are discussed. As terrigenous aromatized pentacyclic triterpenoids are shown as products of eary diagenesis with lower maturity, they provide some crucial information on why the terrigenous triterpenoids or aromatizic triteopenoids have not been so poplary detected and identified in higher Plant-derived oils. |
