METHOD FOR GENERATING A HYBRID PATTERN ALLOWING THE MODELING OF A HETEROGENEOUS FORMATION CROSSED BY SEVERAL LINES

摘要

method for generating a mesh to model heterogeneous hybrid formation traversed by one or more shafts.for example, an underground formation where one or more wells were drilled in order to form a representative model, for example, fluid flows in the environment in accordance with theno numerical scheme is defined.the method consists essentially of the association a first mesh structured to cover the gaps within the heterogeneous environment.a second structured mesh to cover an area of radius around each pipe or shaftthis allows us to better meet specific constraints related to the flow in the area.unstructured mesh, and the transition between the first mesh is interposed and second mesh well.it combines various mesh sizes, each with its own methods, representation and exploration.a structured mesh is advantageous in that they facilitate the control and understanding of the images to be shape of the deposit and the unstructured mesh is more flexible for the maillagthe complex areas. application of oil reservoir simulators, for example.
