A Method for Constructing Regional Geological 3D Models Based on Multi-Source Data Fusion

Abstract

This invention relates to the field of geological modeling technology, specifically to a method for constructing regional geological 3D models based on multi-source data fusion. This method solves the technical problems in existing geological models, such as morphological distortion in areas without boreholes, disconnected topological structures, and inaccurate boundary extraction. The method includes: constructing a multi-source feature field that integrates regional geophysical data and geological structural information; using the multi-source feature field to characterize geological property impedance and geological structural direction; determining the orebody connectivity framework connecting multiple discrete mineralization centers based on the multi-source feature field and multiple discrete mineralization centers; and reconstructing a 3D geological entity model through interface evolution based on the orebody connectivity framework and geological property impedance.
