Abstract

The invention relates to a rapid refined three-dimensional geological modeling method based on multi-source data. The method comprises the following steps: carrying out data fusion processing on drilling data and a geological section; storing a set of spatial three-dimensional points generated after data fusion processing in a unified mode; carrying out autocorrelation judgment on hierarchical data of point data in the database, and then carrying out interpolation encryption to construct a geological point model; determining a boundary range of the modeling area, creating a bounding box capable of accommodating the whole modeling area, then filling the volume elements from top to bottom, and carrying out splitting operation; and storing various types of data generated in the entity model construction process according to a set data structure, and carrying out visual operation on the model. According to the method, the original survey data is fully utilized, the reliability of the geological interface is ensured by selecting a proper interpolation method, and meanwhile, the three-dimensional solid model constructed based on the regular voxel splitting method not only can finely express the interior of the solid, but also can consider the accurate expression of the surface of the geologic body.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional geological modeling, and in particular relates to a fast and refined three-dimensional geological modeling method based on multi-source data. Background technique [0002] With the rapid development of modern cities, people pay more and more attention to the development and utilization of underground space and resources. The construction and expression of underground space model has become a research hotspot. The accurate and detailed 3D geological model can display the thickness, geological structure, lithology, spatial form and other attributes of the stratum more intuitively, and provide accurate information for professionals to analyze the geological structure and fault distribution, so as to provide information for underground space analysis and decision-making. reliable basis. [0003] Traditional geological modeling often uses a single data source. Although some modeling cases in...
