摘要
显微荧光光谱技术具有微区原位测试优势，可弥补生物标志化合物方法难以进行微区测试的不足，已应用于原油物理性质、成熟度、烃源岩、油源对比和成藏期次划分等方面。但是，通常使用的λmax，Imax、Q650/500和Q535等光谱参数尚无明确的地球化学意义，且受到生物降解、层析作用等影响，应用局限性较大。为了优化显微荧光光谱技术，改进其在石油地质研究中的应用效果，在分析显微荧光光谱参数的基础上明确了系统建立荧光光谱参数并揭示其地球化学意义的基本思路，指出了完善荧光光谱参数体系，在生物降解和层析作用下开展油气运移，通过综合测试分析解决荧光光谱法的多解性研究方向。
Microfluorescence spectrum technique has the superiority of in-situ detection in micro scale, thus can make up the disadvantage of biomarker method which can not be used in the microzone detection. The technology has been used in the following study fields ： physical properties of crude oil, maturity, source rock, oil source cor- relation and the classification of reservoir-forming periods. However, the usually used parameters such as λ max, I Q650/500＇ Qf535and SO on have no definite geochemical meanings, and moreover are affected by biodegradation and tomographic action and so forth, thus their applications are limited more seriously. In order to optimize the technology of microfluorescence spectrum and improve its application effects in the studies of petroleum geology, on the basis of analyzing the parameters of microfluorescence spectrum, the above parameters are systematically made clear and furthermore the general ideas of their geochemical significances are disclosed. Finally the following re- search orientations are clarified ： with the help of the improved parameter system, conduct petroleum migration stud- ies on the basis of biodegradation and tomographic action and moreover through the comprehensive test and analy- sis, solve the multi-solution problem of fluorescence spectrum method.
