应用显微光度术、显微傅立叶红外光谱（Ｍｉｃｒｏ－ＦＴ．ＩＲ）和飞行时间二次离子质谱（ＴＯＦ－ＳＩＭＳ）等原位微分析技术并结合均一温度测量对胜利油气区下第三系沙河街组沙三段中有机包裹体进行了研究。区分出两类有机包裹体，即原生有机包裹体和次生有机包裹体。结果表明两类有机包裹体特征不同，二者物质组成、有机质成分及化学结构、热演化程度等差别也较大。结合地质分析表明原生有机包裹体是沙三段烃源岩生成烃类运移产物，具“自生自储”特点，而次生有机包裹体是沙四段烃源岩生成的烃类二次运移的产物。沙三段是沙河街组油气运移和聚集的主要层位，因而是寻找油气资源的主要目标层。研究表明，有机包裹体是研究油气生成、运移、聚集和演化等成藏系统最有效的手段之一，在油气勘探中有重要的应用意义。
In situ microanalysis, microscopic Fourier transform infrared spectroscopy (FT-IR) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) Organic inclusions in the third member of Shahejie Formation were studied. Two types of organic inclusions are distinguished: primary organic inclusions and secondary organic inclusions. The results show that the two types of organic inclusions have different characteristics, and the differences of their material composition, organic matter composition, chemical structure and thermal evolution are also significant. The combination of geological analysis shows that the primary organic inclusions are hydrocarbon generation products from the source rocks of Es 3 member and have the characteristics of “self-generation and self-storage”, while the secondary organic inclusions are secondary hydrocarbon generation from source rocks of Sha 4 Member The product of the shift. The third member of the Shahejie Formation is the main oil and gas migration and accumulation in the Shahejie Formation, and is therefore the main target for the search for oil and gas resources. The results show that organic inclusions are one of the most effective means to study the hydrocarbon accumulation, migration, accumulation and evolution in petroleum accumulation. They are of great significance in oil and gas exploration.
