The invention concerns a method for building a three-dimensional (3D) cellular partition covering a 3D geological domain by defining the cells of the partition, characterized in that said method comprises the following steps A "3D screen construction step" for constructing a 3D screen which is a 3D elementary partition covering the geological domain, said 3D screen being composed of a plurality of voxels (Vi) which are elementary volume elements, A "voxel painting step" for associating a cell identifier (Cell-id) to each voxel, A "cell definition step" for defining the cells of the geological domain, each cell of the geological domain being defined as the subset of voxels of the 3D screen associated to the same cell identifier, thereby allowing the definition of the cells of the geological domain without having to code the geometry and/or topology of said cells in said geological volume. The invention further provides a "parametric" method and a "cookie~cutter" method using such method for building a 3D cellular partition.
L'invention concerne un procédé permettant de construire une partition cellulaire tridimensionnelle (3D) recouvrant un domaine géologique 3D en définissant les cellules de la partition. Ledit procédé consiste à construire un écran 3D qui est une partition élémentaire 3D recouvrant le domaine géologique, ledit écran étant composé de plusieurs voxels (Vi) qui sont des éléments volumiques élémentaires, à associer un identificateur de cellule (Cell-id) à chaque voxel, à définir les cellules du domaine géologique, chaque cellule de ce domaine étant définie comme le sous ensemble de voxels de l'écran 3D associé au même identificateur de cellule, ce qui permet de définir les cellules du domaine géologique sans devoir codifier la géométrie et/ou la topologie desdites cellules dans ledit volume géologique. L'invention concerne enfin un procédé <= paramétrique >= et un procédé de <= l'emporte-pièce >= qui fontappel à un tel procédé de construction d'une partition cellulaire 3D.
