摘　　要：通过对全国各大油田典型油气的分析 ,提出各种油气的三维荧光光谱和固定波长同步荧光光谱特征峰和共性峰。利用三维荧光光谱可以判断油气的属性 ,油气性质的精细分析尚要依靠同步荧光光谱。钻井过程常常加入磺化沥青或原油 ,三维荧光光谱可以进行很好的干扰识别 ;钻遇煤层或含煤层段 ,根据煤的三维荧光等值线图加以判断。人类活动、化石燃料的不完全燃烧均能造成芳烃的污染 ,在取样和处理分析数据时应该进行校正。湖相和海相沉积物含有丰富的多环芳烃 。Based on study on the characterization of three dimension and constant wavelength synchronous fluorescence spectra, the similarity and characteristic peaks of various crude oils and natural gases have been proposed. The types of crude oils and natural gases can be identified by three dimensional contour spectra, but the synchronous fluorescence spectrum could show the small difference between crude oil and oil sand.Three dimensional contour spectra can be used not only in judging polluted samples of synthesizing well log, but also in indicating coal layers. In addition, the pollution that combustion of fossil fuel and mankind actuations had produced will interfere in spectra, so it must be considered when the analytical data are treated. The constant energy synchronous fluorescence spectroscopy offers the advantages of greater sensitivity and selectivity for marine sediments, which contain ample aromatic hydrocarbon molecules, than the constant wavelength synchronous fluorescence spectroscopy.
