MODEL ORDER REDUCTION TECHNIQUE FOR DISCRETE FRACTURED NETWORK SIMULATION

摘要

A method for reducing an order of a discrete fractured network simulation. The method includes receiving cells representing a portion of a subterranean formation that includes a fracture. A first plurality of the cells that correspond to the fracture may be marked as a first cell level. A second plurality of the cells that touch the first plurality of cells may be marked as a second cell level. The first plurality of cells may be grouped into a first superelement. The second plurality of cells may be grouped into a second superelement. One of the first plurality of cells in the first superelement may be designated as a master cell. A volume for the master cell may be updated to include volumes for each of the first plurality of cells in the first superelement.

1. A method for reducing an order of a discrete fractured network simulation, comprising:
receiving cells representing a portion of a subterranean formation that includes a fracture; marking a first plurality of the cells that correspond to the fracture as a first cell level; marking a second plurality of the cells that touch the first plurality of cells as a second cell level; grouping the first plurality of cells into a first superelement; grouping the second plurality of cells into a second superelement; designating one of the first plurality of cells in the first superelement as a master cell; updating a volume for the master cell to include volumes for each of the first plurality of cells in the first superelement; and displaying the master cell after the volumes for each of the first plurality of cells in the first superelement have been included.
