Construction of coherent 3D geological blocks from stratified geological structure

  • Building geometry model of complicated geological entity is important work in exploration and exploitation oil and gas field. With the introduction of geological geometry modeling method, the trend of syncretizing the surface modeling and solid modeling was pointed out, and an integral modeling method based on the TIN model was presented. Data structure of geological block was presented based on improving on half-edge data structure, and the algorithm of constructing coherent 3D geological blocks from completed stratified geological structure and some results was presented. The algorithm is very useful for building the solid model of geological structure and also can be used in several actual projects of forward modeling, ray tracing method and visualization of 3D geological model.
