Pour augmenter le taux de récupération du pétrole, une des solutions chimiques utilisées consiste à injecter des mousses dans les milieux poreux. En effet, les mousses permettent sous certaines conditions de diminuer la mobilité et ainsi d’améliorer le balayage du réservoir. Cependant, les mécanismes contrôlant la mobilité des mousses ne sont pas bien compris. Nous proposons une approche microfluidique permettant une observation directe de l’écoulement des bulles dans un micromodèle de milieux poreux. Nous observons que l’écoulement n’est pas homogène dans le milieu poreux: il se fait uniquement dans quelques chemins. Le nombre de chemins préférentiels dépend de la qualité de la mousse et du nombre capillaire. Si nous simplifions le milieu ...
