针对地化录井或岩屑荧光录井常用的7种有机溶剂进行了荧光光谱分析,对原油在不同溶剂中的溶解程度以及钻井液添加剂、原油和含油岩样的溶剂提取液进行了对比测试研究,结果认为环己烷和正己烷均适用于原油荧光定量分析,二者相比,环己烷更有利于原油荧光显示的辨别。
Seven kinds of organic solvents commonly used in geochemical logging or cuttings fluorescence logging were analyzed by fluorescence spectroscopy. The crude oil solubility in different solvents and the comparison of drilling fluid additives, crude oil and solvent extracts of oil-bearing rock samples were tested. The results show that both cyclohexane and n-hexane are suitable for the quantitative analysis of crude oil fluorescence. Compared with cyclohexane, cyclohexane is more conducive to the identification of the fluorescence of crude oil.
