摘要

三维荧光图谱具有"指纹图"的特征。通过对井中岩屑样品及近地表土壤样品的三维荧光分析,不仅可以指示油气的运移、聚集,而且可以有效地指示油气层的存在及其油气属性,是对于已钻井油气层重新认识(老井油气复查)的有效方法,同时可据其推断下覆圈闭的含油气性质,是地面化探指示油气属性的有效指标。

Abstract

The characteristic fingerprints of three-dimensional fluorescence spectra in we ll-debris and soil samples are described. Determination of well debris and near -surface soil show that the fingerprints not only indicate migration and accumu lation of oil and gas, but also efficiently identify existence of oil and bas fo rmation, and what is more, it can distinguish oil from gas. Therefore, the techn ology of three-dimensional fluorescence spectra fingerprints is a kind of effec tive means in the re-checking of oil wells and the geochemical exploration of o il and gas.
