摘　　要：分子有机地球化学是二十世纪 70年代以来迅速发展的分支学科。它通过分析生物标志化合物 (又称分子化石 )的化学组成及构型转化来研究沉积有机质的演化以及沉积矿产特别是石油的成因。本文简要地介绍了分子有机地球化学方法在为油气勘探提供关于有机质来源、沉积环境、成熟度、油气运移及生物降解等多方面信息中的应用。Organic geochemistry of biomarker is a new developing interdisciplinary branch in geological science since 1970's. Based on the analysis of chemical composition and configuration transformation of biomarkers (or so-called molecular fossils), Scientists got more detailed information on the evolution of sedimentary organic matter and the genesis of depositional resources, particularly on the petroleum. This paper introduces the application of biomarker in petroleum exploration and development, such as input of organic matter, original depositional environment, migration and biodegradation of oil and maturity of source rock.
