Claim:
1. A method for constructing an image of an underground formation traversed by at least one well, the image comprising a stratigraphic mesh including a plurality of stratigraphic units defined by an upper surface and a lower surface, and representing a homogeneous sedimentary layer, the stratigraphic units including a set of cells with each cell being defined by a set of nodes wherein at least one property characteristic of the formation is measured at the level of the well, comprising for each stratigraphic unit: i. setting a depositional position of the stratigraphic unit, by using a computer to determine a position of cell nodes of the stratigraphic unit at a time of deposition of at least one reference surface contained in the stratigraphic unit, by: ii. superimposing with a computer a regular Cartesian grid on the stratigraphic unit in the depositional position; iii. assigning with a computer a value of the at least one property characteristic of the formation to each cell of the grid, from the well measurement, a well in the depositional position and a geostatistical simulation; and iv. transferring with a computer the values assigned to each cell of the grid to cells of the stratigraphic mesh.
