摘要

在分析全国各大油田典型油气的基础上,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。钻井过程常常加入磺化沥青或原油,通过对磺化沥青的三维荧光光谱和固定波长同步荧光光谱特征峰的分析,可以进行干扰因素的识别;原油的加入将抬高整口井钻井岩屑的荧光强度,可以视其为背景而消除。湖相和海相沉积物等含有丰富的多环芳烃,采用恒定能量同步荧光光谱分析效果更佳。此外,处理数据时还要考虑具体的地质情况。

Abstract：

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.Three-dimensional contour spectra and constant-wavelength synchronous fluorescence spectra can be used in judging polluted samples of synthesizing well log by the wavelength and intensity of the emission peaks.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.In addition,the geological information must be considered when the analytical date is applied.
