Tri-dimensional geologic body dynamic reconfiguration method based on sequence profile topology inference

Abstract

The invention is a three-dimensional geological body dynamic restructuring algorithm based on sequence section topology reasoning. Starting with nature-determining space knowledge expression and reasoning, the invention introduces nature-determining space reasoning into the three-dimensional geological modeling, and enhances the comparison dimension of the sections to realize the automatic comparison of sequential sections through the construction and reasoning of quasi-two-dimensional topology among non-shared sequence sections. The invention effectively solves the problems of automatic comparison non-shared sequence sections, partial model upgrading of three-dimensional geological body based on sections, and overall dynamic restructuring of models; greatly reduces the workload of manualinteractive model establishment, avoids the incapability of dynamic upgrading of models, and enhances the model-establishing efficiency of irregular three-dimensional geological body; adapts to data ofa variety of sections and finds wide applications in varied professional software.

Description

technical field [0001] The invention relates to the technical field of geoscience information processing, in particular to spatial reasoning, three-dimensional graphics and three-dimensional geological modeling methods. Background technique [0002] The invention relates to the cognition problem of "geographical space" and "geological space", the description problem of three-dimensional topological relationship, and the problem of automatic modeling and dynamic updating of complex geological bodies. Here, "geographical space" is defined as the space above the earth's surface, and "geological space" is defined as the space below the earth's surface. The main differences between the two are reflected in the following points: [0003] 1. Geological bodies in geological space are generally not visible because they are buried deep underground, and the spatial form data of geological bodies are generally obtained through indirect measurement; while physical objects in geographica...

AI Technical Summary

Problems solved by technology

At present, the 3D solid modeling method in geographic space is becoming more and more mature, but the expression and reconstruction of 3D topology are still in the exploratory stage, and the rapid update and reconstruction of complex models is still a problem to be solved; while in geological space, due to the above There are three differences, especially due to the qualitative and incompleteness of geological data in geological space, the 3D geological body modeling method still stays at the stage of static manual interactive modeling; because it requires too much manual reasoning and judgment based on geological knowledge

[0007] Geological body modeling based on profiles is one of the most basic methods, but because automatic comparison of effective profiles cannot be realized, dynamic reconstruction and local update of the model cannot be performed with this method
