Research On Constructing Way Of 3D Stratum Model Based On Drill Data

Three-dimensional geological modeling (3DGM) is one of the key issues to be solved in the three-dimensional geographic information system (3DGIS) and Digital Mine. Since technology of drill comes out, it was recognized by geologist engineers always in case of having the ability of recording a great deal barbarism information of geology entity cell. Studying the three-dimensional geological model based on drilling data is of great significance for the development of a three-dimensional geological modeling theory and methodology.The paper sums up the main problem in current 3DGM study, such as the absent topology description and the interactive difficult in 3D space; and then analyzes the traditional drill data, 3DGM and the relation between them, and designs the database's interaction operating under computer environment; puts forward a kind of 3D stratum data model oriented object and devise its data construction, implement management module of bore data, 3D visualization of bore data, By object-oriented 3D geological model and design their drilling data structure, the construction process of model is clear, and can integrate with the object-oriented programming language, at the same time the models on Delaunay triangle network constructs topo relations of both two-and three-dimensional data, greatly simplifies complex topo relations between 3D geological bodies; achieves drilling data management module, the drilling data 3D visualization; researches on 3D geological body of space enquiries methods, achieving mutual enquiries with graphics attributes some functional by...
