Abstract

The invention discloses a method for dynamically constructing a three-dimensional formation model, which involves displaying virtual reality technology on a display screen, comprising the following steps: integrating formation data; defining formation data and selecting regions; data selection; determining modeling construction Regional scope; judge and improve data; construct grid insertion point; generate data structure; form 3D model. The invention has the advantages of playing an important auxiliary role in urban construction, especially in the acquisition of underground space information and construction schemes in the construction of future smart cities. Promote the three-dimensional development of urban space and the development and utilization of underground commercial traffic; fully develop and utilize the protection potential of underground space resources. At the same time, in the geological research of underground mineral deposit development, 3D modeling can play a more prominent role in geological research.

Description

technical field [0001] The invention relates to displaying virtual reality technology on a display screen, in particular to a method for dynamically constructing a three-dimensional stratum model by simulating the distribution of strata to realize the construction of a stratum data model and improve the efficiency of urban underground space planning. Background technique [0002] What is a stratigraphic model? The stratigraphic model is a 3D mesh. These grids are based on surface layers, faults and horizons. It determines the structure and geometry of the reservoir. Each node in the grid has a set of properties, such as porosity, permeability, water saturation, etc. A stratigraphic model (pattern) is a simplified expression and comprehensive interpretation of the composition, structure, and space-time existence of a stratigraphic entity. The most common stratigraphic model is a section model in which the composition, structure, and depositional environment of the interva...
