应用显微光度术、显微傅里叶红外光谱（Micro－FT．IR）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。有机包裹体荧光特征和显微傅里叶红外光谱定量研究表明：（1）原生有机包裹体中含有硫醇化合物，其烃类有机质烷基碳链较长，碳原子数约为15-17;次生有机包裹体中除含有硫醇外，还含有一定量的H2S，其烃类有机质烷基碳链较短，碳原子数约为5—6；（2）原生有机包裹体热演化程度比次生有机包裹体热演化程度低，与均一温度测量结果一致（前者为87-91℃，后者为98—105℃）；（3）原生有机包裹体和次生有机包裹体的成分和热演化程度分别与沙三段和沙四段烃源岩特征和有机质生烃热演化程度相符合。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与直接证据。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、聚集和演化最有效的手段之一。
The organic inclusions in the third member of the Shahejie Formation in the Lower Triassic of Shengli Oil and Gas Region were studied by means of photomicrograph and micro-FTIR combined with uniform temperature measurement. Two types of organic inclusions are distinguished: primary organic inclusions and secondary organic inclusions. Quantitative study on the fluorescence characteristics and Fourier transform infrared spectroscopy of organic inclusions shows that: (1) The primary organic inclusions contain thiol compounds with long alkyl carbon chains of hydrocarbon-based organic matter with carbon atoms of about 15-17. In addition to containing mercaptan, the secondary organic inclusions contain a certain amount of H2S, which has a shorter alkyl carbon chain and a carbon number of about 5-6. (2) The extent of thermal evolution of primary organic inclusions The degree of thermal evolution of the secondary organic inclusions is low, consistent with the measurements of the homogenization temperature (87-91 ° C for the former and 98-105 ° C for the latter); (3) the composition and heat of the primary and secondary organic inclusions The evolution degree accords with the characteristics of hydrocarbon source rocks and hydrocarbon evolution of organic matter in Es3 and Es4, respectively. 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 move and direct evidence. 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. Research shows that organic inclusions are one of the most effective means to study the formation, migration, accumulation and evolution of oil and gas.
