Abstract

Cette invention concerne la simulation d'un réservoir souterrain d'hydrocarbures avec un puits horizontal ou de multiples puits verticaux par résolution séquentielle d'équations de réservoir et de puits pour simuler l'écoulement de fluide à l'intérieur du réservoir et les taux de production de puits. La résolution séquentielle d'équations de réservoir et de puits traite les puits comme des puits à pression de fond spécifique. Ceci permet d'éviter la résolution de grandes matrices résultant de la résolution simultanée des équations de réservoir et de puits, qui peut être informatiquement très coûteuse pour grand nombre d'inconnues et nécessiter des résolveurs spéciaux par matrice creuse. Une telle résolution séquentielle met en œuvre des résolveurs normaux de système de réservoir complétés par de petites matrices pour la résolution numérique des pressions de fond de trou. La résolution est effectuée sur des matrices tridiagonales pour les cellules de réservoir adjacentes aux intervalles de puits perforés ; et un vecteur des potentiels de réservoir inconnus pour les cellules de réservoir adjacentes.
