Abstract
Several of Algerian oil reservoirs are now at the end of their lifeeventhough most of the oil is still in place. The implementation of an enhanced oil recovery method can yield a substantial amount of additional oil. The present work deals with a study of two natural crude oils : one coming from the Mesdar field and the other from the Zarzaitine field. After a classical PVT study of two crude oils alone, the same measurements were carried out with many mixtures oil injection gas . In a second step, displacements of both oils in an artificial porous medium were performed, and minimum miscibility pressures (MMP) were measured with different gases. Finally, a numerical simulation was carried out by means of a new SIGMA-COREmodel to simulate the displacements.
L'Algérie possède plusieurs gisements d'huiles qui arrivent en fin d'exploitation malgré d'énormes réserves enfouies dans son sous-sol. L'application d'une des méthodes de récupération assistée du pétrole peut laisser espérer un gain appréciable de production. Le présent travail a porté sur l'étude de deux huiles naturelles : l'une venant du gisement de Mesdar et l'autre de Zarzaïtine. Après une étude PVT classique des deux huiles seules, les mêmes mesures ont été poursuivies avec divers mélanges huile + gaz d'injection . Dans une deuxième étape, les essais de déplacements des deux bruts dans un milieu poreux artificiel ont été réalisés avec les différents gaz, dans le but de déterminer les pressions minimales de miscibilité (PMM). Enfin, des simulations numériques ont été effectuées à l'aide du modèle SIGMA-COREpour simuler les déplacements.
