激光拉曼光谱法分析多种显微组分荧光变化及其应用

利用激发488 nm激光的氩离子激光器作为RENISHAW inVia型激光拉曼光谱仪的光源,建立了多种显微组分荧光变化(FAMM)分析方法,并对镜质体反射率明显抑制的东营凹陷有效烃源岩进行了测定。结果表明,东营凹陷有效烃源岩的有机质类型越好,镜质体反射率抑制程度越高,有效烃源岩的真实成熟度应主要处于0.64%~1.30%,而不是实测镜质体反射率所反映的0.37%~1.10%。

Laser Raman Spectrometric Analysis for Fluorescence Alteration of Multiple Macerals and Its Application

The fluorescence alteration of multiple macerals(FAMM) analysis approach is established by using argon ion laser with 488 nm as light source of laser Raman spectrograp and used in analysis of effective source rocks from Dongying depression with significantly suppressed vitrinite reflectivity. The results show that the better of organic matter type is, the higher of level of vitrinite reflectivity suppression is. The true thermal maturity of effective source rocks from Dongying depression is mainly at 0.64%~1.30% instead of 0.37%~1.10% from actual measurements.
