Method of optimizing the development of a fluid reservoir by taking into account a geologic and transient exchange term between matrix blocks and fractures

摘要

Method for optimizing the development of a fluid reservoir by taking into account a transient exchange term between porous blocks and fractures. The reservoir is discretized into a set of grid cells and an image representative of the fracture network delimiting porous blocks and fractures is associated with each cell. A transient exchange flow occurring between the porous blocks and the fractures is then determined at each cell by processing the image representative of the fracture network. Fluid flows in the reservoir are simulated by means of a flow simulator and of this exchange flow, and development of the reservoir is optimized by means of this fluid flow simulation.
