The nonlinear flowing rule in low permeability reservoirs can be described entirely with the nonlinear mathematical model. The theoretical calculation method of flow pattern distribution is proposed. Flow pattern distribution under the influence of injection-production pressure
injection-production well spacing and formation permeability in low permeability reservoirs is analyzed in this paper. The model proposed here also describes the pressure distribution characteristics of fluid flow in extra-low velocity in low permeability reservoirs
which corrects former misunderstandings of the characteristics.
