FI技术在油气地质研究中的应用新进展

流体包裹体(FI)为研究油气地质提供了一种崭新的思路、方法和手段。通过分析流体包裹体的类型、特征、丰度、均一温度、盐度、压力和成分，可以了解油气热演化程度，为油气生成时的物理化学条件和流体的来源等研究提供重要信息；在油气运移、聚集过程中，温度与成分等特征发生相应的交化，通过对不同阶段所捕获的FI的研究，可以确定油气的运移时间和深度，探明油气运移的通道和方向，评价油气资源潜力以及预测油气的勘探远景区。此外，作还用流体包裹体势图和流体包裹体地层学方法，从宏观上描述了油气的运聚方向和通道，指出了其会聚的最有利区段，为直接指导油气的勘探提供理论依据。

Progress on Application of Fluid Inclusion in Petroleum Exploration Geology

In the past ten years, much attention was paid to the application of fluid inclu sions to the study of petroleum geology. This paper reviews many previous studie s on the type,abundance,temperature,paleosalinity and constituent, the proces ses of hydrocarbon generation, migration, evolution and reservation from lots of recently published works and literatures. A number of researche and experimenta l data show that the inflow times, depths and paths of hydrocarbon-bearing flui d from basin sedimentary rocks can be attained using FI technology. Some petrole um geologists have successfully applied FI technology to assessment of the reso urce potential and to the identity of the oil/gas exploration targets. In order to help readers understand FI is useful to petroleum geological researches, we g ive an example about our study of the hydrocarbon-bearing fluid inclusions in t he Dezhou depression in Linqing basin, Shandong Province.
