Abstract

In order to increase the production of oil in low permeability reservoirs with high efficiency, it is necessary to fully understand the properties and special behaviors of the reservoirs and correctly describe the flow in the reservoirs. This paper applies the branching network mode to the study of the starting pressure gradient of nonlinear Newtonian fluid (Bingham fluid) in the reservoirs with low permeability based on the fact that the fractured network may exist in the reservoirs. The proposed model for starting pressure gradient is a function of yield stress, microstructural parameters of the network. The proposed model may have the potential in further exploiting the mechanisms of flow in porous media with fractured network.
