塔里木盆地陆相原油二环倍半萜烷系列中，Ｃ１５补身烷低于Ｃ１６升补身烷（Ｃ１５／Ｃ１６＜１．０），重排二环化合物丰富。这些原油的三环萜烷以低碳数（Ｃ１９～Ｃ２１）化合物占优势，（Ｃ１９＋Ｃ２０＋Ｃ２１）／（Ｃ２３＋Ｃ２４）＞１．４；其中湖相油以Ｃ２１为主峰，煤成油以Ｃ１９为主峰。五环三萜烷中普遍富含Ｃ２９，Ｃ３０重排藿烷和Ｃ２９Ｔｓ及一个未知的Ｃ３０五环三萜烷。它们有较丰富的长链类异戊二烯烃，其中煤成油含有较高的Ｃ２７～Ｃ３９头对头系列。海相原油在这些生物标志物分布上则完全不同。
In the ternary sesquiterpene series of terrestrial crude oils in the Tarim Basin, the C15-complement alkane is less than C16-liters (C15 / C16 <1.0) and the rearranged bicyclic compounds are abundant. The tricyclic terpanes of these crude oils dominated by low carbon number (C19 ~ C21) compounds, with C19 + C20 + C21 / C23 +> 1.4. Among them, C21 was the main peak in lake oil and C19 was the main oil in coal. Pentacyclic triterpenes are generally rich in C29, C30 rearranged hopane and C29Ts and an unknown C30 pentacyclic triterpene. They have more abundant long chain isoprenoids, of which coal to oil contains a higher C27 ~ C39 head to head series. Marine crude oil is completely different in the distribution of these biomarkers.
