【摘要】 本文利用红外、紫外及荧光分析方法，对岩石中吸附有机质和包裹体有机质进行了分析研究。红外分析结果表明：生油岩中的包裹体有机质有明显的石油峰，并且与吸附有机质的峰形有较大差别。紫外分析结果也表明：生油岩中两种有机质的光谱性质不一致，而非生油岩则相反。生油岩荧光光谱特征为：荧光强度大（＞40）λmax在450nm左右，光谱位于蓝绿光区，演化程度属高成熟原油阶段。这些可作为评价生油潜力、演化程度的方法及指标。更多还原

【Abstract】 Studies have been done on adsorbed organic matter and inclusion organic matter in rocksby using the infrared, ultraviolet and fluorescence analytical methods. IR analytical results showthat there are obvious oil peaks due to inclusion organic matter in oil-generating rocks, which aresignificantly different in peak shape from those of adsorbed organic matter. Ultraviolet analyticalresults demonstrate that there are two types of organic matter which are characteriszed by differ-ent spectral characteristics in the oil-generating rocks, the opposite case is observed in non-gener-ating rocks. Fluorescence spectral characteristics of the oil-generating rocks are: strong fluores-cence intensity (>40), around 450 nm, and spectra being located in the blue-green light region,indicating a high-maturity oil stage. The infrared, ultraviolet and fluorescence analyses can be used as a combined method and index to evaluate the oil-generating potentiality and evolutionary extent of organic inclusions.更多还原
