Three-dimensional geological overburden layer interface modeling method and device, equipment and storage medium

Abstract

The invention discloses a three-dimensional geological overburden layer interface modeling method and device, equipment and a storage medium. According to the method, the gradual change principle of ageological overburden layer is fused into an interpolation calculation method in a mathematical function mode for the first time, and therefore, during overburden layer interface modeling, triangularmesh interpolation points can consider the boundary characteristics of a geologic body and the logic relationships of upper strata at the same time, and the modeling calculation requirement of a three-dimensional geological overburden layer interface is met; different fitting functions can be set; the fitting functions can be used for describing the geologic body of the overburden layer in a gradual change mode, and therefore, the characteristics of boundary line nodes are embodied, logic relations between newly-added nodes and known exploration points are also covered, the three-dimensionalgeologic overburden layer interface can be described more accurately, and modeling precision is improved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional geological modeling, and in particular relates to a three-dimensional geological overburden interface modeling method, device, equipment and storage medium based on triangular grids. Background technique [0002] In the field of 3D geological modeling technology, triangular grids are often used to fit the geological interface in 3D space. When calculating and fitting a single 3D geological interface, methods such as kriging are used to calculate the coordinate values ​​of the remaining interpolation nodes based on known node coordinates, such as figure 1 As shown, because it does not involve the boundary characteristics and the logical association between the upper and lower layers of the multi-interface, it can basically meet the calculation requirements. [0003] However, when combining the surface with the modeling of geological overburden interface, coupled with the range of three-d...

Problems solved by technology

[0003]However, when combining with the ground surface to carry out geological overburden interface fitting modeling, plus the range of three-dimensional geological overburden interface modeling, traditional mathematical interpolation calculation methods cannot characteristics, and logical analysis and judgment related to the surface, which cannot meet the modeling and calculation requirements of the 3D geological overburden interface
