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 extending between two successive geological events, the method comprising the implementation by data processing means (21) of steps of: (a) obtaining measurements of physical quantities of said basin acquired from sensors (20); (b) for each of said states Ai, constructing a mesh representation of the basin in accordance with said measurements of physical magnitudes; (c) For each of said states Ai, and for each mesh of the meshed representation, 1. calculating an effective stress applied to the mesh at the end of the state Ai; 2. calculation of an overpressure in the mesh at the end of the state Aien function of said effective stress calculated at the end of the state Ai.
