| 摘 要： | 激光拉曼光谱(LRM)是一种研究物质分子结构的微观分析技术，文章在总结LRM在油气资源勘探研究中的应用的基础上，对油气田样品中的流体包裹体(FI)、有机质成熟度以及岩石中分散有机质类型进行了研究。认为LRM不仅可以对样品中单个流体包裹体各相态的成分、岩石中微量残留有机质类型进行定性的研究，而且还可以对单个流体包裹体各相态成分及镜质体反射率进行定量化研究。结果表明，用ωB％NaCl=61．183S-22．173计算盐水包裹体的盐度和通过拉曼光谱参数(D)用公式R0(％)：0．69ln(82．12D-16 054．49)-4．88求镜质体反射率(R0)是可行的。

| Abstract: | Laser Raman Microprobe (LRM) is a micro-analytical technique for determining molecular components. Based on the summarization of the applications of LRM in petroleum exploration, the authors analyzed fluid inclusions (FI) and organic matters, and found that this technique could not only research qualitatively different phase components of single fluid inclusions and the types of organic substances, but also determine quantitatively each phase component of single fluid inclusions and the indexes of maturation of vitrinite. It is concluded that it is feasible to calculate the salinity of single FI by to sigmaB % NaCl = 61.183S - 22.173 and the reflectance (R0) of vitrinite by R0 (%) = 0.69 ln(82.12 D - 16,054.49) - 4.88. |
