Automatic updating method and system for three-dimensional geological structure model based on GIS platform

Abstract

The invention discloses an automatic updating method and system for a three-dimensional geological structure model based on a GIS platform. The method comprises the steps of dividing a modeling area of the three-dimensional geological structure model into a plurality of subareas; acquiring a plurality of pieces of drilling data in each sub-region, and determining relevancy and related factors among the plurality of pieces of drilling data; obtaining updated three-dimensional geologic structure model parameters, obtaining multiple pieces of drilling data in each sub-region again, and determining new relevancy and related factors among the multiple pieces of drilling data; and comparing the new relevancy and correlation factor in each subarea with the relevancy and correlation factor beforeupdating, and determining the subarea needing parameter updating, thereby realizing updating of the three-dimensional geologic structure model. The method has the beneficial effects that the detectionpart adopts a real-time acquisition mode to quickly analyze and process the modeling data in real time, so that the three-dimensional geological structure model can be quickly, efficiently and automatically updated.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a method and system for automatically updating a three-dimensional geological structure model based on a GIS platform. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the development of society and national economy, geological disaster investigation and evaluation, early warning and mineral resource reserves are becoming more and more important. At present, although my country's land and resources departments have achieved remarkable results in geological surveys and geological prospecting, they have encountered many technical difficulties in the course of their work, especially in the exploration of complex geological bodies. In order to meet the exploration requirements of complex geological bodies, the 3D model is used t...

Problems solved by technology

In 2D modeling, the modification only affects the local area; while in 3D modeling, the local modification requires related models to be rebuilt, and the model reconstruction work brought about by the modification in the 3D modeling process greatly affects the efficiency and quality

However, the 3D modeling method in the prior art is fixed. Even if it is updated, it is manually updated through new data, and the automatic update of the modeling data cannot be completed quickly and efficiently in real time.
