【摘要】：钻孔岩芯高光谱扫描和编录对传统的地质编录具有重要参考价值。针对当前面扫式成像光谱仪在钻孔岩芯编录技术方面研究的不足,提出了一套基于图谱合一成像光谱数据的钻孔岩芯编录技术方法。以Hyspex地面成像光谱仪为数据源,对采集的一个整孔岩芯高光谱图像数据进行图像处理和矿物填图;通过设置岩芯段统计单元,利用图像像元分类统计的方法分段计算岩芯矿物相对含量数据;经过数据滤波处理,最终获得了钻孔垂向空间上各种矿物的相对含量编录曲线,实现了矿物在钻孔垂向空间上的定量化表达。经地质编录验证了结果的合理性,并能够弥补传统地质编录在精细化和定量化程度方面的不足,提高深部蚀变分带的客观性和可靠性。
[Abstract]:The hyperspectral scanning and cataloguing of borehole cores have important reference value for traditional geological cataloguing. This paper presents a method of borehole core cataloging based on the spectral data of atlas and imaging. The data of a whole pore core hyperspectral image is processed and the mineral mapping is carried out with Hyspex ground imaging spectrometer as the data source. The relative content data of core minerals are calculated by using the method of image pixel classification and statistics, and the relative content cataloging curves of various minerals in vertical space of boreholes are obtained by filtering the data. The quantitative representation of minerals in vertical space of boreholes has been realized. The rationality of the results has been verified by geological cataloguing, and the shortcomings of traditional geological cataloguing in terms of refinement and quantification can be made up. Improve the objectivity and reliability of deep altered zones.
