甾烷
The sterane isomerization maturity parameter and alkylphenanthrene index indicate that the maturity of oil sand is low. 甾烷的異構(gòu)化成熟度參數(shù)、甲基菲指數(shù)均顯示油砂成熟度低。
It is found that C(28)(20S)/C(28)(20R) ratio in triaromatic sterane seems to show good thermal evolution characteristics. 我們發(fā)現(xiàn)三芳甾烷C(28)(20S)/C(28)(20R)比值似乎顯示了較好的熱演化特征。
The crude oils of Chang 20 belong to typical immature oil which have odd even predominance and lower ratios of sterane and terpane maturity index. 從長20井低熟原油中檢測到了一定量的28,30二降藿烷,這說明源巖形成于極度厭氧的環(huán)境。
We also bring forward a new method to recognize the different biological source for C29 sterane predominance using organic carbon isotope. 此外,本文還提出了用有機碳同位素來進一步區(qū)分C29甾烷優(yōu)勢生物來源的方法。
This paper mainly sums up recent identification of biomarks(sterane,diterpane)in the crude oil and source rock with GC/MS/DS. 本文報道我們近幾年來利用色質(zhì)聯(lián)用儀對原油及生油巖中生物標志物(甾烷、萜烷)的定性分析鑒定。
