三维荧光指纹技术及其在石油地球化学勘探中的应用

THREE DIMENTIONAL FLUORESCENT FINGERPRINT TECHNIQUE AND ITS APPLICATION TO PETROLEUM EXPLORATION

作者对三维荧光指纹分析技术进行研究。提出原油及有关样品三维荧光指纹图的共性指标T_1(Ex228nm/Em340nm)和差异指标(S、X、K、F、R),并将指纹图分为O、B、Q、P四种类型,这些共性指标和差异指标有利于鉴别样品的荧光异常,可为油/油对比、油/岩对比、地表化探应用等提供可靠的依据。

Studying the three dimentional fingerprint analysing technique, the author proposes the similiarity indexes T1(Ex228nm/Em 340nm) and the differential indexes (S,α,K,F,R) for the three dimentional fingerprint graph of crude oil and related samples, and the finger graph is divided into four types i. e. O,B,Q,R. These nidexes are favourable to differentiating fluorescent abnormalities, providing solid basis for correlations of oil /oil, oil/source rock, and application to surface chemical exploration, etc.
