Abstract

L'invention concerne un procédé de détermination de la saturation résiduelle d'un premier fluide dans un milieu poreux à l'injection d'un deuxième fluide dans ledit milieu poreux comprenant les étapes suivantes: a) On place au moins un échantillon dudit milieu poreux imbibé par ledit premier fluide, dans une centrifugeuse à une gravité effective g* pendant une durée de centrifugation t, ledit deuxième fluide étant injecté par ladite centrifugeuse ; b) On mesure la saturation résiduelle au premier fluide dudit échantillon par Résonance Magnétique Nucléaire ou par pesée immergée ; c) On répète les étapes a) et b) en faisant varier la valeur de ladite gravité effective g* ; d) On construit une courbe de saturation résiduelle du premier fluide dudit milieu poreux à l'injection dudit deuxième fluide à partir de chaque saturation résiduelle mesurée pour chaque valeur de ladite gravité effective testée g*. L'invention concerne également un procédé de récupération assistée d'hydrocarbures dans un milieu poreux, utilisant ledit procédé de détermination de la saturation résiduelle.The invention relates to a method for determining the residual saturation of a first fluid in a porous medium upon injection of a second fluid into said porous medium comprising the following steps: a) at least one sample of said porous medium is placed impregnated with said first fluid, in a centrifuge at an effective gravity g * for a centrifugation time t, said second fluid being injected by said centrifuge; b) The residual saturation in the first fluid of said sample is measured by Nuclear Magnetic Resonance or by submerged weighing; c) Steps a) and b) are repeated, varying the value of said effective gravity g *; d) A residual saturation curve of the first fluid of said porous medium on injection of said second fluid is constructed from each residual saturation measured for each value of said tested effective gravity g *. The invention also relates to a method for the enhanced recovery of hydrocarbons in a porous medium, using said method for determining the residual saturation.
