Abstract: The paper considers simulation techniqies for flow simulation within discrete fracture network systems accouting for fluid flow along vuggs associated with fractures intersections. A mathematical model is described for two-phase flow within fractured vuggy reservoir accounting for flow exchange between fractures and vugs, capillary and gravitational forces. Capillary forces are described by Young-Laplace model, which takes into account rock wettability, surface tension, fracture aperture and vug cross section diameter. The appropriate numerical simulation techniques are presented. The influence of flow within vugs on water-oil displacement process in fractured vuggy reservoir with various wettability conditions is explored by numerical simulation. It is shown that the presence of vugs at the intersections of fractures in certain conditions may provide a significant influence on displacement indicators.
Keywords: fractured vuggy reservoir, multiphase flow, capillary forces.
