Fremgangsmåte for kinematisk, todimensjonal modelldannelse av geologiske bassenger

摘要

Method to model from an initial, undeformed state, the evolution of a geological tank in the course of time, taking into account of the sliding along the discontinuities major tectonics, with deformation of the inside of the sediments and b) of the mechanical compaction due to the burying of the sediments tectonics, by deformation or sedimentation. (br / after a preliminary subdivision of the geological objects of the pool in a certain number of layers or banks, by the limits (discontinuities stratigraphic delimiting the benches, faults delimiting the scales, etc.) which is known, the geometric position, is discretized by the banks of the grids, it determines the deformation tectonics of each layer made in the better its thickness and its length, and it modifies the meshes to take account of the compaction associated to the variations of burying of the elements knitted. All the intermediate configurations of the process of development are obtained of incrementally. The model obtained makes it possible to take account of the variation of the permeability of the expulsion of the fluid by the compaction and heat transfers to the scale of the basin by the circulation of fluids. & br / application to the location of underground reservoirs of hydrocarbons.
