| 摘 要： | 本文运用流体包裹体方法，基于薄片观察和岩矿学研究，探讨了四川盆地碳酸盐岩大型气田的气源。首先对包裹体的生源属性、多期捕获和后生变化进行了精细的鉴别分析。在此基础上，通过成岩自生矿物微量元素、包裹体相组成、均一温度、初熔温度等参数鉴别多期演化的油气充注。通过烃类包裹体化学成分初步鉴别出煤成气和油型气。根据烃类包裹体的相组成鉴别有机质可能来源于腐泥型源岩还是腐殖型源岩。最后根据同期包裹体生物标志物确定某一期次的油气所对应的烃源层。结果表明研究成果符合地质实际，为传统的油气源追踪对比研究提供了一个重要有效的辅助方法。

| Abstract: | Based on section observation and petro-mineralogy research, gas source of large gas fields of carbonate in Sichuan
Basin are probed into with fluid inclusion method. First, the autogenecity, multistage and re-equilibrium of inclusion are subtly distinguished. Based on this, oil-gases of different stages are distinguished according to microelements of autogenetic minerals, phase composition, homogenization temperature of inclusions and water medium conditions. The humic gas and sapropelic gas are primarely differentiated with quantitative laser raman microfrobe spectroscopy. The source (humic or sapropelic rocks) of organic matter in inclusions are distinguished according to phase composition and distributing characteristics of inclusions. In the end, source rock stratum of a certain period oil-gas are ascertained with the biomarkers of corresponding inclusions. The result indicate that researchful conclusions accord with geological facts, which provide an important and effective method for the conventional research of oil-gas source trace. |
