The embodiment of the invention provides a method, device and apparatus for determining a digital rock core, and the method comprises the steps: obtaining a plurality of two-dimensional images of a crystal rock, with the plurality of two-dimensional images being images corresponding to a plurality of abrasion surfaces of the crystal rock, and the plurality of abrasion surfaces being obtained through the equal-interval abrasion of the crystal rock; determining a three-dimensional image corresponding to the crystal display rock according to the plurality of two-dimensional images; obtaining a grayscale image of the three-dimensional image; and determining a digital rock core of the crystal display rock according to the gray scale intervals corresponding to the multiple preset components andthe gray scale values of the pixels in the gray scale image, with the digital rock core comprising the component proportions of the preset components in the crystal display rock and the spatial distribution information corresponding to the preset components. The accuracy of determining the digital rock core is improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of geological science and technology, and in particular to a method, device and equipment for determining a digital rock core. Background technique [0002] At present, the phamorphic structure rock (also referred to as phamorphite) is a commonly used engineering material. For example, phamorphite can be used as a material for nuclear waste landfill, a reservoir for developing geothermal resources, and the like. [0003] In practical application, in order to better use phenancrite in engineering scenarios, it is usually necessary to obtain digital cores of phenancrite (for example, the composition ratio of each preset composition, the spatial distribution information corresponding to the preset composition wait). In the prior art, the X-rays are usually used to perform tomographic scanning of the phenancrite by computerized tomography (CT) imaging technology, and the three-dimensional image ...
