吡咯类化合物及其在油气运移中的应用

Pyrrolic Compounds and Application in Hydrocarbon Migration

阐述了石油地质体中吡咯类化合物的基本地球化学性质、分离与分析方法、分布形式、地球化学意义(如成熟度、沉积环境、原始母质等)和运移作用的影响。综述了国内外吡咯类化合物的研究现状及应用实例,认为吡咯类化合物在油气运移方面的研究和应用,极大地推动了非烃地球化学的发展。同时指出该化合物在油气运移研究和应用中存在的一些局限性,如原油样品必须来自同一油源,成熟度对其相对分布的影响方式与影响程度还不清楚等。

The basic geochemical property, the separation and analysis techniques, distribution pattern and geochemical significance (i.e., maturity, sedimentary environment and original source material, etc.) of pyrrolic compounds in petroliferous geologic bodies and the effect on hydrocarbon migration are presented. The recent research state and the applying cases at home and abroad are reviewed. It is pointed out that the research and application of pyrrolic compounds to petroleum migration greatly promote the development of non-hydrocarbon geochemistry. Also, some limitations of the compounds application to the petroleum migration are given, such as that the crude sample should be obtained from the same kitchen; and how the maturity influences on its distribution is unknown yet.
