Research on the application of large area 3D geological modeling splicing technology

Abstract

Three-dimensional geological modeling is widely used in the field of geological research. A successful three-dimensional geological model is a three-dimensional anatomy and integration of the study area. Large-scale three-dimensional geological modeling is limited by software performance and technical difficulties. There are disadvantages such as unequal model splicing elements, morphological distortion and attribute incompatibility. Based on the discrete storage method of DepthInsight software, this paper explores the large-area model fusion and splicing technology to deal with various geological conditions, and carries out large-area multi-block model fusion and splicing from the aspects of element type, quantity and attribute. The large-area 3D geological modeling technology scheme of discrete storage and block splicing is realized, which provides a reference for establishing a large-area 3D geological model.
