摘　　要：油层中流体必须克服一定压力后才能流动，这种压力即为流体渗流时的启动压力．本文从流变学原理出发，推导出低渗透油藏流体渗流启动压力的理论计算公式。该方法计算简便，易于科技人员掌握使用，从而为油田开发部署提供一定依据。Fluid must overcome certain pressure before it can flow in oil reservoirs, this pressure is defined as the starting pressute of fluid percolation.Based on rheological principles, this paper derives a theoretical formula for calculating the starting pressure of fluid percolation in low- permeability reservoirs.It is simple and easy to use and can provides scientific basis for disposition of oil field development plan.
