The Equivalent Numerical Simulation of Fractured-Vuggy Carbonate Reservoir

Abstract:

The storage spaces of carbonate reservoir are complicated, matrix pores, vugs, fractures and large caves are coexistence. Traditional numerical simulation methods have harsh requirement for geology model and computing method, these methods are not suitable for carbonate reservoir. A comparatively perfect equivalent permeability and porosity model for multi-media reservoir was developed based on the theory of equivalent continuum media and the law of equivalent seepage resistance. The equivalent parameters of a practical reservoir were calculated by this model, and a numerical simulation was carried out by using these parameters, the results showed that the equivalent numerical simulation of fractured-vuggy carbonate reservoir was reasonable.
