method for the modeling and simulation on a larger scale, the development of kohlenwasserstoffbrunnen

摘要

- Method of modeling the acidification within a porous medium after the injection of a acid. - we construct a double medium model, by considering a first - medium suitable for the openings of dissolution, and a second - a medium which is not favorable to the openings of dissolution. For each of these under - media, a description of the metric scale of the transport of the acid, of the storage of the mass of the medium under - and the acid, and the transfer of an acid medium under - to - medium. It is then subtracted from this double medium model from settings experimental. Finally, thanks to this double medium model are modelled the acidification of the mixture, - application in particular to the use of oil deposits.
