Three-dimensional modeling method of hyperspectral information of deep rock and mineral

Abstract

The invention belongs to the field of earth science and technology, and particularly relates to a three-dimensional modeling method of hyperspectral information of deep rock and mineral. The method specifically includes the following steps: step one, hyperspectral measurement of a drilling core; step two, standardization of spectral data; step three, parameter calculation of a spectral measurementfunction; step five, importing of a three-dimensional geological modeling environment; step six, establishment of a three-dimensional geological grid model; step seven, construction of a three-dimensional variogram model; step eight, Kriging three-dimensional spatial interpolation; and step nine, three-dimensional visualization. The method uses the advantage of fine and quantifiable rock and mineral information identification of hyperspectral technology of the drilling core, simulates a development degree of the deep rock and mineral in a semi-quantitative manner through the spectral measurement function, the three-dimensional variogram and the Kriging three-dimensional spatial interpolation on the basis of hyperspectral data which is of the drilling core and is obtained by a hyperspectral meter, and has the advantages of high modeling efficiency, fine model characterization, quantification and the like.
