摘　　要：一般低渗透油田,随着开发的深入有效渗透率会逐渐下降,启动压力梯度上升,注水难度随地层压力的下降不断增加,这对注水开发十分不利。研究有启动压力梯度的低渗透油田的渗流规律,指导低渗透油田开发,尤其是注水开发具有重要意义。目前启动压力的研究主要有三种方法:室内物理实验模拟方法,数值实验方法和试井解释方法。本文主要利用试井解释方法结合质量守恒定律来计算启动压力。The effective permeability will drop gradually and the staring pressure gradient will increase with the further development in conventional low permeability oilfield. With the drop of formation pressure, the water - flooding becomes more and more difficult, it is harmful to water- flooding development. It has great significance to study seepage rules of low permeability oilfield with starting pressure gradient especially for water - flooding development. At present, there are three methods to study starting pressure that is in - house physical experimental simulation, numerical experimentation and well test interpretation. Here, starting pressure is calculated by the combination of well test interpretation method and mass conservation law.
