石油的长期生成演化在油储外围介质中留下了反映油气存在的“指示物”。对这些介质取样的激光诱导荧光光谱分析研究表明,激光荧光光谱可以揭示油砂、钻井岩心、浅层水、土壤等油气藏外围介质中所含的油气“指示物”——芳烃,且不同激发波长所对应的介质取样荧光光谱反映着不同的油气芳烃组份。这对于用光谱分析法开展大面积找油具有指导意义。
The long-term evolution of petroleum has left an “indicator” of oil and gas presence in the oil reservoir peripheral medium. Laser-induced fluorescence spectroscopy analysis of these media samples shows that laser fluorescence spectroscopy can reveal the “indicator” of aromatics contained in the peripheral media of oil and gas reservoirs such as oil sands, drilling cores, shallow water and soil, and different excitation Fluorescence spectra of the medium samples corresponding to the wavelengths reflect different hydrocarbon aromatics components. This is of great instructive significance for the large-area oil discovery by spectral analysis.
