Method and apparatus of a grid comprising a device for simulation of a grid of the surface structure designed to be used by a simulator of the reservoir

摘要

A simulation gridding apparatus includes a structured gridder and a horizon in an earth formation including one or more fault intersection lines comprises; (a) a boundary enclosure around the fault intersection lines on the horizon; and (b) a structured areal gridder adapted for building a structured areal grid over the boundary when the fault intersection lines are enclosed by the boundary. The structured area includes intersecting stream lines with a number of nodes, and at least some of the streamlines including control lines, the control lines including fault intersection lines. Also claimed is a method for constructing a structured simulation grid and a device for storing instructions to be executed by a computer in order to perform the above simulation.
