摘要
生物标志物地球化学是７０年代以来迅速发展起来的分支学科。它通过分析生物标志物的化学组成及构型转化来研究沉积有机质的演化及沉积矿产特别是石油的成因。本文以我国东部油田下第三系生油岩及原油中生物标志物的分布为例，简介了它们为油气勘探提供有关有机质来源、沉积环境、成熟度、油气运移及生物降解等多方面信息的重要作用及其新的进展。生物标志物，地球化学，构型，油气勘探，成熟度，运移。
Geochemistry of biomarker is a new developing branch science since 1970's.Basedon the analysis of chemical composition and configuration transformation of biomarkers,theevolution of sedimentary organic matter and the genesis of depositional resources,particularly the petroleum,have been studied.Taken the distribution of biomarkers in Tertiary sourcerock in East China as an example,this paper displays its important role and some advances byproviding the information about input of organic matter,original depositional environment,maturity of source rock as well as migration and biodegradation of oil.
