Abstract

-Fremgangsmåte for rask simulering av strømning av ett enkelt, inkompressiblelt fluid i et heterogent porøst medium så som en akvifer eller et petroleumsreservoar. · - Etter å ha diskretisert mediet ved hjelp av et beregningsnett definerer vi et permeabilitetsfelt fra hvilket diffusjonslikningen løses direkte i frekvensområdet med en iterativ metode som omfatter FFT. Tre algoritmer foreslås avhengig av de konkrete forholdene som behandles. Den første algoritmen, som behandler trykkene og hastighetene direkte, er generell, men den kan være langsom ved store permeabilitetsvariasjoner. Den andre algoritmen, som innfører en mellomvariabel som oppdateres i hver iterasjon, muliggjør raskere behandling av store permeabilitetsvariasjoner. Videre tillater den større permeabilitetsvariasjoner enn den første algoritmen. Den tredje algoritmen, som er basert på økning av en Lagrangemultiplikator, gjør det mulig å behandle uendelige permeabilitetsvariasjoner. Disse forskjellige algoritmene muliggjør simulering av strømningene i svakt til sterkt heterogene medier, med redusert beregningstid. Anvendelse: for eksempel utvikling av petroleumreservoarer.
