含油气盆地流体包裹体分析的关键问题和意义

Key Questions of the Fluid Inclusion Analysis in Petroliferous Basins and their Significances

油气生成运移和成藏过程会在岩石中留下烃类流体包裹体,对这些微尺度的流体化石记录进行岩石学和地球化学分析,为反演油气成因和运移成藏提供了重要信息。本文回顾了含油气盆地流体包裹体分析和解释的基本原则,结合国内外油气包裹体分析和研究进展,分析讨论了流体包裹体在油气成藏过程研究中应用的关键问题,包括：油气成藏过程是否有完整的流体包裹体记录;如何从烃类流体包裹体识别油气藏、古油气柱和运移途径;从流体包裹体分析油气成藏期次和古压力,油气包裹体成分分析等问题,并讨论了如何实现流体包裹体数据与其他不同尺度和分辨率的数据融合和相互约束,规范含油气盆地流体包裹体分析和解释技术,提高流体包裹体在分析油气运移成藏中的价值。

Hydrocarbon fluid inclusions were reserved in the rocks in processes of hydrocarbon generation,migration and accumulation. The petrological and geochemical analyses of these microscale fluid fossils will provide important information for the inversion of hydrocarbon genesis and migration into reservoirs. This paper has reviewed basic principles for the analysis and interpretation of the hydrocarbon fluid inclusion in the petroliferous Basin,summarized the analysis and research progress of petroleum and gas inclusions at home and abroad,and discussed some key questions of the application of fluid inclusions for studying hydrocarbon accumulation process. They include whether there are complete records of fluids inclusions for whole oil and gas accumulation processes,how to identify hydrocarbon reservoir,paleo oil and gas columns and migration pathways based on the study of hydrocarbon fluid inclusions,how to probe the accumulation times and paleopressures of the oil and gas by studying fluid inclusions,and how to analyze the composition of hydrocarbon fluid inclusions.Furthermore,This paper also has discussed how to make combination and mutual restraint of fluid inclusion research data and data of other research methods at various scales and resolutions,how to promote the specification for fluid inclusions analysis and interpretation,and how to improve the application value of the fluid iclusions for studying the migration and accumulation of the petroleum and gas.
