Abstract

Abstract This is the basis of the formation of the whole 3D geological model. The geological structure surface model subsystem is mainly based on the geological structure surface data provided by the borehole and the virtual borehole. The Delaunay triangulation algorithm is used to construct the TIN model to fit the geometric structural surfaces of various geological objects, such as stratigraphic interface and fault plane. 3D visualization modeling of geological structure is a complex problem, which needs to be explored continuously. The research and application show that the idea of 3D geological modeling based on GOCAD breaks through the limitation of two-dimensional representation of complex terrain surface and underground structure. A more intuitionistic and accurate 3D geological model is provided, which meets the practical requirements and is gradually popularized in application.
