岩屑荧光图象采集的原理是岩屑在荧光灯的照射下,基于石油有机成分都发荧光的特点采用高分辨率的数字成像技术及机电一体化设备采集岩屑发光物质,获取岩屑荧光数字图象。该项技术一是改变以往人工定性描述、经验判断的局面,实现定性判断到定量应用的飞跃,二是准确识别荧光下含油岩屑百分含量及白光下各种颜色的百分含量,三是为综合解释评价油气层提供依据,完善油水层解释评价方法。通过该项技术的现场应用,实现了岩屑录井的数字化,可以在现场对储层进行初步解释评价,并为完井综合解释评价油气层和生产决策提供了可靠依据,对综合解释评价油气层和录井技术的发展有很重要的意义。
The principle of the debris fluorescence image acquisition is that the cuttings are fluoresced on the basis of the organic components of the fluorescence under the fluorescent lamp. High-resolution digital imaging technology and mechatronic equipment are used to collect the cuttings luminescent materials and obtain the fluorescence figures Image. The first technology is to change the past qualitative description of human nature, the experience of judging the situation, to achieve qualitative judgments to the quantitative application of the leap, the second is accurate identification of fluorescent oil shale percentage and white under various color percentage, the third is To provide a basis for the comprehensive interpretation and evaluation of oil and gas reservoirs and to improve the interpretation and evaluation method of oil and water layers. Through the field application of this technology, the digitalization of cuttings logging is realized, the reservoir can be preliminarily explained and evaluated in the field, and a reliable basis can be provided for the comprehensive interpretation and evaluation of well completion and production decision. Layer and logging technology development is of great significance.
