MODELING FLUID-CONDUCTING FRACTURES IN RESERVOIR SIMULATION GRIDS

摘要

Systems, methods, and media for modeling fluid-conducting fractures in reservoir grid simulations. The method includes determining a model of an underground reservoir. The model includes one or more conductive fractures and a grid of three-dimensional (3D) reservoir cells. The method also includes determining the 3D reservoir cells that intersect the conductive fracture. The method further includes determining two-dimensional (2D) fracture cells representing the conductive fracture in the model. Additionally, the method includes determining fluid flow through the conductive fracture using fluid flow parameters of the plurality the 3D reservoir cells intersecting the fracture and fluid flow parameters of the 2D fracture cells. Further, the method includes updating the model based on the fluid flow.
