在地球化学中,油气藏是自然界中相对集中的巨大烃源。油气藏中的烃类通过扩散-渗透-水动力方式不断地向油床上方及其附近的地下水和土层提供烃源。在烃类中,单环、双环乃至稠环芳烃是石油的重要组分,且为荧光物质。当这些物质因地壳的运动向地表迁移时,浅部地下水易于捕集这些反映地下水中油气存在的信息,因此,通过荧光法来测量石油中这类稠环芳烃组分的含量,并建立含量与地下油气贮集间的相应关系,在石油化探工作中是一项有意义的研
In geochemistry, reservoirs are relatively concentrated large hydrocarbon sources in nature. Hydrocarbons in hydrocarbon reservoirs continuously provide hydrocarbon sources to groundwater and soil layers above and near the oil bed by diffusion-permeation-hydrodynamic methods. In hydrocarbons, monocyclic, bicyclic or even condensed aromatic hydrocarbons are important components of petroleum and are fluorescent substances. As these materials migrate to the surface due to crustal movement, shallow groundwater tends to capture these messages that reflect the presence of oil and gas in groundwater. Therefore, the content of such PAHs in petroleum is measured by fluorescence spectroscopy and the content and The corresponding relationship between underground oil and gas storage is a meaningful research in the geochemical exploration work
