摘要:

生烃母质的结构及其演化特征是石油地球化学研究的重要课题之一,随着新的分析测试方法的出现,生烃母质结构组成的研究已从基本的元素分析向官能团分析方向发展。固体核磁共振13C(NMR)分析已成为研究物质结构及其演化的一种有效手段,它可以测定不同类型含碳官能团的定量分布,从而计算各种结构参数,提供有关碳骨架最直接的重要信息。将这些结构信息从烃源岩的生烃潜力评价、烃源岩的生烃演化过程及机理、烃源岩的热演化判定等角度考虑实际存在的地质问题,发现脂族碳是油气的主要贡献者,油气潜力碳含量的高低决定了烃源岩生烃潜力的大小,芳核平均结构尺寸是有效的热演化衡量标尺。固体13C核磁共振分析为石油地球化学的研究打开了新局面。

Abstract:

The structure and evolution characteristics of hydrocarbon generation material is an important problem for the study on petroleum geochemistry. With the occurrence of new analysis method, the component and structure study of hydrocarbon generation material has been made large development which is froming the element to functional groups analysis. The solid state 13C NMR spectroscopy gives the content of different functional groups, further, the every kind of structure parameters can be calculated. The structure information has been made a new analysis from the angle of the evaluation of source rocks, the hydrocarbon generation evolution and mechanism of source rocks, and the maturity indicators of source rocks, etc. It has been calculated that the aliphatic carbon is the major contributor of oil and gas, the content of oil and gas potential carbon determinated the hydrocarbon generation potential of source rocks, and the average aromatic cluster size is an effective and recommendable evolution indicator. The solid state 13C NMR techiniques open a new field for the study on petroleum geochemistry.

Key words: Solid state 13C NMR    Oil and gas potential carbon    Potential of hydrocarbon generation of source rocks    Structure parameter.
