Direct Inspecting of Solid Powder Fluorescence of Oil Cuttings

采用自主搭建的荧光检测系统,利用光纤作为传感组件,对含油岩芯固体粉末样品进行荧光光谱的直接检测,其发射波长、激发波长都得到了可与在溶液中测量相比拟的实验结果。通过对含油岩芯固体粉末的直接检测,以及采用高斯拟合方法对含石油岩芯样品的多组分进行分析,得到了相应荧光光谱的特征参数,从而可以分析含油岩固体粉末的相关特性。这种方法为快速直接分析含石油岩芯特性提供了一种新的有效途径。在采用这种新方法的同时,探讨了固体粉末中能量转移困难对于样品荧光造成的影响。

Using the fluorescence inspected system and optic fiber, the solid powder fluorescence of oil cuttings is inspected directly. Experimental results are similar with the results measured in solution, such as the emissive and excitation wavelength. The corresponding fluorescence spectroscopy parameters are obtained by inspecting the solid powder of oil cuttings directly, and analyzing the samples of multi-component by Gaussian fitting method. And the characteristics of the solid powder of oil cuttings are analyzed. It provids a new way to analyze the characteristics of the oil cuttings quickly and directly. At the same time, the impaction of the difficulty of energy transfering in the solid power on the excitation of fluorescent is also discussed.
