定量荧光录井技术是近年来新兴的一门录井技术,该技术在排除钻井液对岩屑污染、识别真假油气显示方面有其独特的作用。本文从图谱特征、差谱方法等对利用定量荧光录井技术降低钻井液污染对录井资料影响方法进行了探讨。 Quantitative fluorescent logging technology is a new logging technology emerging in recent years. It has its unique function in removing debris from drilling fluid and identifying true and false oil and gas. In this paper, the method of using quantitative fluorescence logging technique to reduce the influence of drilling fluid pollution on mud logging data is discussed from the features of spectra and difference spectrum.
