This paper describes a new approach for simulating the flow of water, oil and gas in fully or partially fractured reservoirs. This approach is based on the dual porosity concept and uses a conventional tridimensional-triphasic black oil model with minor modifications. The basic feature is that an elementary volume of the fractured reservoir is simulated by several model cells : the matrix is concentrated into one ''matrix cell'' and the fractures into the adjacent ''fracture cells''. ''Fracture cells'' offer a continuous path for fluid flows while ''matrix cells'' are discontinuous (chess board display). The matrix-fracture flows are directly calculated by the model, taking into account capillarity, gravity, pressure difference between the matrix blocks and fractures and pressure gradients across the matrix blocks.
