METHOD FOR OPERATING A SEDIMENT BASIN HAVING HYDROCARBONS USING STRATIGRAPHIC MODELING

摘要

A process for exploiting hydrocarbons within a sedimentary basin, using stratigraphic simulation coupled with a hydrological model and a diagenetic model. For at least one time step, by means of a stratigraphic simulator, a meshed representation of the studied basin comprising at least one mineralogical composition and a porosity within each mesh is determined. Then, by means of a hydrological model, at least one hydrological zone is defined and at least one chemical composition of the fluids and a flow direction of the fluids are determined in each of the cells located in the zone. Then at least the fluid chemistry, the mineralogical composition and the porosity in each of the meshes of the meshed representation are updated by means of a diagenetic model comprising a hydrological flow balance, established by means of at least one of the circulation directions. fluids and from which is determined a flow order of the meshes by the fluids, and comprising a kinetic reaction model, modeling the interactions between the chemical composition of the fluids and the mineralogical composition in the mesh. Application in particular to the exploration and the oil exploitation.
