Improved three-dimensional geological modeling method based on Kriging interpolation

Abstract

The application relates to an improved three-dimensional geological modeling method based on Kriging interpolation, which comprises the following steps: S1, obtaining drilling plane coordinates and the elevations of stratum interfaces corresponding to the plane coordinates; S2, determining the plane coordinates of interpolation points, performing Kriging interpolation on the elevations of the same stratum interface, and obtaining the coordinate data of each stratum interface after interpolation; S3, generating a virtual interface, and obtaining the peripheral contour line of each virtual interface; S4, obtaining the bottom surface and the top surface of a geological model; S5, generating a terrain entity between the bottom surface and the top surface of the geological model; S6, segmenting the terrain entity based on the virtual interfaces of each stratum to obtain a layered terrain entity model; and S7, distinguishing the parameters of each layer model in the layered terrain entity model. Compared with the prior art, the application has the advantages of improving the modeling effect of three-dimensional geological modeling.
