Method of determination of the residual saturation of a first fluid in a porous medium as a result, at the injection of a second fluid.

摘要

The present invention relates to a method for determining a curve of the saturation of the residual s * or of a first fluid in a porous medium, after the injection of a second fluid in the porous medium. The curve is constructed from a number of trapping n1 * obtained by means of the measurement of the distribution volume of the size of the lymph nodes of the fluid in the porous medium. The present invention also relates to a process for the assisted recovery of hydrocarbons, for which it is possible to determine the saturation curve in the residual hydrocarbons in the porous medium.
