3D Geological Modeling in Digital Basin

D geological model, including structure model and attribute model, is the basis of building a 3D digital basin. This paper analyzed the models and their applicated model types involved in digital basins construction. In digital basins structure model is expressed by TIN surface, and attribute model is expressed by voxels. Divided the level of model and its expression range in digital basin. Taking into account the construction of digital basins, detailed the 3D geological modeling flow of oil and gas reservoir, and focused on the structure modeling of the process.
