Provincial domain level 1: 500000 three-dimensional geological modeling method and system

Abstract

The invention provides a provincial domain level 1: 500,000 three-dimensional geological modeling method and system, provides a complete and feasible provincial domain level 1: 500,000 three-dimensional geological modeling process at an altitude of 2500 meters or shallower, deepens a cross section at an altitude of 2500 meters or shallower and an interval of 10 Km based on a provincial domain 1: 500,000 longitudinal modeling stratigraphic unit, drilling data and a basic geological map, and provides a provincial domain level 1: 500,000 three-dimensional geological modeling method and a provincial domain level 1: 500,000 three-dimensional geological modeling system. Covering a geologic modeling area in a provincial domain range through a series of cross sections; dividing the modeling area into different modeling blocks on the basis of following the structural occurrence by adopting a pseudo-fault partitioning method and based on a fault system; establishing a three-dimensional geologic body structure model of each modeling block by utilizing in-block geological knowledge driving and geological element reasoning, and completing three-dimensional geologic body framework modeling at a provincial level of 1: 500,000 altitudes to 2500 meters; and in combination with three-dimensional geologic body attribute modeling, an attribute model is coupled with a grillwork model, and a grillwork and attribute integrated three-dimensional geologic body model is formed to realize provincial domain-level ultra-deep and ultra-large-scale geologic body modeling.

Description

technical field [0001] The present invention relates to the field of geological information science and technology, in particular to modeling of geological bodies in industries such as glass globe, provincial glass globe, urban geology, mine geology, oil and gas geology, disaster geology, urban geology, environmental geology, hydrogeology, etc. A provincial-level 1:500,000 3D geological modeling method and system. Background technique [0002] Since the 21st century, with the rapid increase in demand for resources due to global integration, technological informatization and urbanization, mankind has entered an era of unprecedented rapid development, and the development and utilization of natural resources on the surface or shallow surface can no longer meet the needs. The demand for resources and space is increasing, and the pressure on resources and the environment is also increasing. In order to effectively alleviate this pressure, foreign developed countries have begun to...
