Geological structure dimension reduction model modeling method based on drilling data

Abstract

The invention discloses a geological structure dimension reduction model modeling method based on drilling data. The method comprises the steps of drilling data generation of drilling stratum three-dimensional points, symbolization of the drilling stratum three-dimensional points, construction of a stratum Delaunay triangulation network, triangular surface elimination based on a cross rule and structural surface generation. According to the method, a dimensionality-reduced stratum structure surface model can be rapidly constructed based on drilling data, stratum structure characteristics including stratum cusp, stratum repetition and the like are visually judged, priori knowledge is provided for three-dimensional modeling, the position of a profile map needing to be added is pre-judged, and area pre-judgment of a special structure possibly exists is pre-judged; the method is suitable for geologic structure modeling for quickly browsing stratum distribution, three-dimensional geologic modeling auxiliary pre-judgment and the like.

Description

technical field [0001] The invention relates to the field of geographic information systems, specifically a method for quickly constructing a geological structure model by using a geoinformation algorithm, which can quickly generate a dimensionality-reduced surface structure of a geological body based on borehole data, and a geological structure dimensionality reduction model based on borehole data modeling method.

AI Technical Summary

Problems solved by technology

[0004] Geological body modeling algorithms are complex, relying on a large amount of data and rich operational knowledge, and modeling takes a long time

On the other hand, due to the deviation of the operator's understanding of the drilling information and the differences in the modeling methods, the 3D geological models constructed are also different.
