摘要

摘要: 近年来有机包裹体在石油地质领域中的广泛应用, 为油气勘探与评价注入了新的活力.有机包裹体特别是油包裹体的荧光颜色是鉴定有机包裹体和指示油气成熟度的有效手段.本文在论述有机包裹体荧光机理的基础上, 依据不同盆地样品的实验观测结果, 从油包裹体荧光的强度、波长、颜色以及与有机包裹体同期的盐水包裹体的均一温度等关系进行分析, 证明可以运用油包裹体荧光颜色和平均均一温度等综合指示油气的成熟度.

Abstract: In recent years, organic inclusion technique has been extensively applied to petroleum exploration. The fluorescence is also a good measurement in identifying oil inclusions and an effective indicator of its maturity, except for some oil inclusions of lower homogenization temperature with white-blue fluorescence color which have been possibly caused by heating decomposition after trapping. In this study, many samples from two basins have been measured to obtain the fluorescence colors and the differences between homogenization temperatures of the coeval aqueous inclusion and oil inclusion, which proves that there is a positive relationship between the fluorescence colors and the averaged homogenization temperature of oil inclusions, and can be reliably used to indicate the hydrocarbon maturity in spite of the fact that some researchers think that it is dangerous to apply visual description of fluorescence colors to determine maturity of hydrocarbon.
