| description | The invention relates to a method of reconstructing a gridded three-dimensional image in the surroundings of a borehole for a first physical magnitude that is measured as a function of depth. The method comprises the steps consisting in: using a two-dimensional image (2) established on the wall of the borehole of a second physical magnitude measured in said borehole as a function of depth and of azimuth; establishing a relationship (3) between the first and second physical magnitudes; and deducing a gridded three-dimensional image (8) of said first physical magnitude in the surroundings of the borehole from said relationship. It is possible to begin by using the values of the second physical magnitude as measured as a function of depth and of azimuth to deduce therefrom a gridded three-dimensional image (6) of said magnitude, and then from said image and using the relationship between the first and second physical magnitudes, to deduce the gridded three-dimensional image of the first physical magnitude in the surroundings of the borehole. The invention is applicable to measuring permeability. |
