摘　　要：拉曼光谱仪在地学中主要用于分析矿物、流体包裹体及生物化石等的结构及组分。用于流体包裹体测试时能直接获得其成分及含量,还可进一步了解成岩过程中流体包裹体所在地层的温度及压力等参数。因此,拉曼光谱可提供研究流体性质、沉积环境及成藏期次所需的重要依据。利用拉曼光谱可进一步认识烃类在纳米级孔隙中的充填及成熟情况,为估算页岩气原始地质储量提供有力证据,目前对有机纳米孔隙所捕集的烃类进行定量分析仍有待进一步研究。In geosciences, Raman spectroscopy is mainly used in analyzing the structure and composition of minerals, fluid inclusions and fossil organisms. It can discover the composition and content of fluid inclusions directly and nondestructively, as well as the reservoir pressure anti paleotemperature during the diagenetic process. Therefore, Raman spectroscopy can facilitate the research in characterization of reservoir fluids and depositional environments, and provide more reasonable determinations of the timing of oil generation. The use of Raman spectroscopy can give us a better understanding of organic carbon nanostructure which is a key point for estimating the oil and gas in-place. However, it would require further investigation to evaluate the amount of hydrocarbons held within organic porosity using Raman spectroscopy.
