Abstract: front page image
(EN)A block model constructing method for complex geological structures is provided. The method comprises the following steps: a) making a triangle mesh description of a layer plane or a fault plane; b) judging whether two triangles intersect, and finding out the intersection points if they intersect; c) performing a geometric consistency and topological consistency processing within every intersectant triangle; d) extracting an enclosing block to acquire an interface constituted of peripheral edges of the enclosing block, and defining a geological attribute of the enclosing block to form a three-dimensional model block. The method needs not to solve difficult equation sets with large computation, thus simplifying the constructing method.
(FR)L'invention concerne un procédé de construction d'un modèle de blocs pour structures géologiques complexes. Le procédé comprend les étapes suivantes : a) faire une description d'un plan de couche ou d'un plan de faille au moyen d'un réseau de triangles; b) estimer si deux triangles se croisent, et, le cas échéant, trouver les points d'intersection; c) mettre en œuvre un traitement de cohérence géométrique et de cohérence topologique à l'intérieur de chaque triangle de croisement; d) extraire un bloc fermé afin de former une interface constituée des arêtes périphériques du bloc fermé, et définir un attribut géologique du bloc fermé pour former un bloc modèle tridimensionnel. Le procédé rend superflue la résolution d'ensembles d'équations difficiles nécessitant un grand nombre de calculs, ce qui simplifie le procédé de construction.
