Ore body modeling method, device and system based on borehole data and storage medium

Abstract

The invention discloses an ore body modeling method, device and system based on borehole data and a storage medium. The method comprises the following steps of carrying out the discrete sampling on borehole data sampled by geological exploration to obtain discrete sampling points; extracting the sampling points of a sample section and converting into contact point constraints; extracting the sampling points of a non-sample section and converting into out-of-plane point constraints; constructing a discrete point distance field according to the contact point constraint and the out-of-plane pointconstraint; spatially interpolating the distance field of the discrete points to construct an implicit function distance field which is used to characterize the distribution of the distance field ofthe ore body boundary; sampling the distance field of the implicit function and calculating based on a reference isosurface extraction algorithm to obtain a three-dimensional model of the ore body. The ore body 3D modeling can be carried out directly based on the borehole data, which saves the troubles of manual interpretation of ore body profile and effectively improves the efficiency and qualityof ore body modeling.

Description

technical field [0001] The invention relates to the field of ore body three-dimensional modeling, in particular to an ore body modeling method, device, system and storage medium based on drilling data. Background technique [0002] Existing 3D modeling of ore bodies generally adopts explicit modeling methods of ore bodies based on manual interpretation of section wireframes for contour line splicing or triangulation reconstruction. This approach to explicit modeling of ore bodies has long been considered "best" industry practice since the ore body can be constrained to a certain shape or lithology. However, the ore body explicit modeling method has inherent defects such as complicated interactive process, inability to dynamically update the progressively refined model, and poor quality of the generated model. Therefore, it is urgent to design a new ore body modeling method to effectively improve the efficiency and quality of ore body modeling. Contents of the invention ...
