Fremgangsmåte for modelldannelse av et lagdelt og frakturert geologisk miljö

摘要

- the method comprises a modeling of the medium by the plies (s (i)) having an orientation substantially common representing the actual stack of layers, and a representation of the fractures in the form of portions of surface, such as a deformable quadrilateral, each passing through at least one of the strata, each portion of the surface being positioned and its extension, delimited by the draw while respecting the densities of fracturing n (i) per unit length of each layer, as well as the proportions (s (i / i + 1), s (i / i - 1)) of fractures through the interfaces between the layers, these densities and proportions are determined by studying the medium (observations direct, photographs, etc..). The model obtained makes it possible to flow simulations fluids likely to move through the medium. & br / - application to the study of the displacements of hydrocarbons in the underground reservoirs, for example.
