摘要

利用非线性数学模型，能够全程描述低渗透油藏的非线性流动规律，从理论上给出了低渗透油藏中流态分布的计算方法，分析了注采压差、注采井距和地层渗透率对流态分布的影响，指出了流体在低渗透油藏中以特低速度流动时压力分布的特点，纠正了前人在这个问题上的认识失误。实际岩芯的渗流试验检验了理论的正确性。

Abstract

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.
