摘要

为探索激光诱导时间分辨荧光光谱技术应用于海洋悬浮溢油原位探测的可行性, 对来自胜利油田六个不同井区不同密度的原油样品的时间分辨荧光光谱进行了探测分析。 结果发现, 各原油样品荧光发射的持续时间基本相同, 从ICCD中数字延时发生器(DDG)的输入延时52 ns开始, 到输入延时82 ns左右结束, 各原油样品的荧光峰强度随时间变化曲线的半高宽约10 ns; 不同原油样品的最强荧光峰位及其衰减寿命不尽相同, 并且与样品密度有一定相关性, 密度相近的原油具有相近的最强荧光峰位和相似的荧光寿命。 对比六种原油样品的时间分辨荧光光谱发现, 在荧光增强时, 原油荧光光谱峰位不变, 当荧光从最大强度开始衰减时, 六种原油样品的荧光光谱峰位均出现了不同程度(17~30 nm)的红移现象, 这一定程度上反映出原油中各荧光组分的荧光衰减速率存在差异, 或者存在荧光组分之间的能量传递。 所观测到的原油密度相关的时间分辨光谱信息和荧光峰红移现象可望成为水下悬浮溢油识别的有效特征之一。

Abstract

To evaluate the feasibility of laser induced time-resolved fluorescence technique for in-situ detection of underwater suspended oil spill, extensive investigations have been carried out with different densities of crude oil samples from six different wells of Shengli Oilfield in this work. It was found that the fluorescence emission durations of these crude oil samples were almost the same, the Gate Pulse Delay of DDG (Digital Delay Generator) in the ICCD started at 52ns and ended at 82ns with a width (FWHM) of 10 ns. It appears that the peak location and lifetime of fluorescence for different crude oil samples varied with their densities, and those with similar densities shared a similar lifespan with the closer peak locations of fluorescence. It is also observed that the peak of fluorescence remained the same location before reaching the maximum intensity, subsequently shift to longer wavelength as fluorescence attenuated from maximum intensity with a red shift among 17~30 nm varied with samples. This demonstrated that the decay rate of fluorescent components in the crude oils was different, and energy transfer between these components might exist. It is hoped that those obtained results and characteristics could be the useful information for identification of suspended spilled-oil underwater.
