Abstract

The subsurface geological structures are considerably complicated, which often appear in the form of normal fault, reverse fault, fold, pinchout and irregular body etc. In order to model geometrically the face structure of the geologic horizon and fault, some key algorithms including the Delaunay subdivision and limited Delaunay subdivision are applied to examine techniques such as curved surface intersection, division, suture, united output and so on, while the compatibility of the complicated geological structure, such as geologic horizon and fault, were maintained on geometry and topology. The analysis proposes the geometric distribution factors of geological object model for the further 3D modeling of the complicated geological object.
