摘要
针对定量荧光录井中存在的有机物荧光干扰问题,文章通过室内消除干扰的模拟实验,提出了消除干扰的两种方法,一种是直接采用荧光谱图的差异区分混入的有机物与地层含油荧光的干扰,另一种是利用荧光差谱及相当油含量的变化落实显示。经过实例应用得到了较好的效果。有利于定量荧光录井技术在现场的油气解释和评价。
To counter organics fluorescence interference problems occured during quantitative fluoresence logging,the paper provides two methods to eliminate interference through laboratory simulation test of eliminating interference,one is directly adopting the difference of fluorescence spectrum pattern to distinguish the difference between mixed organics fluorescence and the formation oil-bearing fluorescence,the other is using fluorescence differential spectrum and the variation of equivalent oil content to decide shows.It has achieved the better results through samples analysis and is beneficial to in-situ oil-gas interpretation and evaluation for quantitative fluorescence logging technology.
