METHOD FOR MODELING A SEDIMENT BASIN

摘要

The invention relates to a method for modeling a sedimentary basin, said sedimentary basin having undergone a plurality of geological events defining a sequence of states {Ai} of the basin, each of said states extending between two successive geological events, the method comprising implementing by data processing means (21) steps of: (a) obtaining measurements of physical quantities of said pool acquired from sensors (20); (b) for each of said states Ai, constructing a mesh representation of said basin according to said measurements of physical quantities; (c) For each of said states Ai, and for each mesh of said meshed representation, calculating an overpressure in the mesh at the end of the state Ai by solving an equation of the Darcy equation type; characterized in that step (c) comprises a preliminary step (c) .0 verification that for at least one of said meshes the overpressure has varied during the state Ai of more than a first predetermined threshold, and of setting the continuation of step (c) only if this is verified.
