Method for building a fracture network mesh from a Voronoi diagram

摘要

The method involves constructing a Voronoi diagram of a fracture network plane by positioning centers (C1, C2) of Voronoi cells on intersection segments. Values of transmissivity between the centers of the neighboring cells are calculated from a ratio between a surface of the neighboring cells and distance between the neighboring cells. The cells and the transmissivity values are used to construct an image of a fluid reservoir. The image of the reservoir and a flow simulator are used to optimize operation of the reservoir.
