摘要
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。
The fluorescence analysis is taken on seven kinds of organic solvents commonly used in cuttings fluorologging or geochemistry logging. The dissolvability of crude oil in various solvents, as well as the solutions of drilling fluid additives, crude oil and oil-contained cuttings extracted by the above solvents,are tested. It is shown that although both cyclohexane and hexane are suitably used in quantitative fluorescence analysis of crude oil, the former is superior to the latter in recognition of crude oil fluorescence.
