METHOD OF ASSISTANCE IN GEOLOGICAL MODELING BY GROUPING MESHES TOGETHER

摘要

The present invention relates to a method of assistance in geological modeling by grouping meshes together in a geological model comprising a plurality of meshes, each mesh of said model being associated with at least one digital parameter representing a geological property. For at least one column of at least n meshes of the model, a plurality of decompositions of said column into m subsets of adjacent meshes can be determined. Then, for each composition determined, one determines, for each one of the m subsets, a new digital parameter associated with said subset depending on the digital parameters associated with the meshes of said subset. Finally, one can determine a dispersion value of said decomposition depending, at least, on the new digital parameters associated with said subsets.

1. A method for assistance in modeling a geological subsoil in a meshed geological model of one to three dimensions,
the geological model including a plurality of mesh cells, each mesh cell of said model being associated with at least one numerical parameter (G00, G01, G02) representing a geological property, the method including the steps: for at least one column of at least n mesh cells of the model:
a/ determining a plurality of decompositions of said column into m subsets of adjacent mesh cells, m being a positive or zero integer less than or equal to n;for each decomposition determined:
a1/ for each of the m subsets, determining a new numerical parameter associated with said subset as a function of the numerical parameters associated with the mesh cells of said subset;a2/ determining a dispersion value of said decomposition as a function, at least, of the new numerical parameters associated with said subsets determined in step a1/; andb/ supplying said decompositions associated with their dispersion value, wherein n is a strictly positive integer.
