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（萘系列、菲系列等），以及丰富的来源于高等植物的芳香二萜和劳构化的五环三萜。目前，原油中芬构化五环三萜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。
Aromatic biomarkers in the tertiary rocks and crude oil from the third member of the Yitong graben in Jilin Province are studied in detail, including the conventional polycyclic aromatic hydrocarbons (naphthalene series, phenanthrene series, etc.) as well as the aromatic aromatic diterpenoids And labor of pentacyclic triterpenoids. At present, there are still few reports on the bioactive constituents of petrochemically modified pentacyclic triterpenes in crude oil at home and abroad. Also discussed in detail the use of aromatics in the discovery of the latest pentacyclic triterpenoid in the area of biological input, oil source contrast and the significance of such aspects of oil.
