Method for modeling a stratified and fractured geologic environment

摘要

An improved method for modeling a stratified and fractured geological environment is disclosed. The method produces a geometric model of a multi-layered fractured sedimentary medium by performing the steps of obtaining from the medium data relating to fracturation densities n(i)per unit of length in different layers of the medium and interruption densities s(i/j) of fractures in each layer (i) interrupting at interfaces with adjacent layers (j); forming a stratified model having a plurality of strata S(i) with fractures represented as traces across each stratum; and positioning each trace with a determined fractural extension by randomly selecting the measured fracturation densities n(i) and interruption densities s(i/j).
