摘要

作者在柴达木盆地西部第三系中采集了19个油样和24个岩样

对这些样品中的二环倍半萜和三环二萜进行了研究。作者认为:二环倍半萜可能来自五环三萜和细菌活动产物;树脂衍生物三环二萜的相对丰度取决于湖水盐度

也与成熟度有关。

Abstract

Using GC/MS technique

the authors studied the dicyclic sesquiterpanes and resin acid-derived tricyclic diterpanes of the Tertiary saline-lake sedi-ments and crude oils in the Qaidam Basin.It is considered that the dicyclic sesquiterpanes may mostly come from pentacyclic triterpanes and the productsof bacteria activity;the input amount of resin derivatives was controlled by salinity of the lake water;hydrocarbon generation of resin acid took placein the early stage of thermal degradation of kerogen.So the hydrocarbon ge-nerated was enriched in low matured oil.
