在石油的长期演化过程中,其中的一些芳烃组分如苯、酚、蒽等,就要通过各种途径运移到地表,形成地球化学异常场。色谱法和化学元素分析法是目前常用的研究地化异常的方法。自1981年起,我们从事采用紫外吸收光谱法分圻地化异常的研究,取得了一些成果,从而为浅层水荧光光谱分析法的提出奠定了基础。 浅层水样取自民用井和或机井,分别经环已烷和氯仿萃取后,测量他们对应三种不同激发波长(N, During the long-term evolution of petroleum, some of the aromatic components such as benzene, phenol and anthracene will migrate to the surface through various routes to form geochemical anomalies. Chromatography and chemical elemental analysis are the most commonly used methods for studying geochemical anomalies. Since 1981, we have done some research on the abnormalization of groundwater by ultraviolet absorption spectroscopy, and have made some achievements, which laid the foundation for the proposal of shallow water fluorescence spectrometry. Shallow water samples were collected from civilian wells and wells or wells, respectively, after cyclohexane and chloroform extraction, measuring their corresponding three different excitation wavelength (N,
