摘要
在异常高压油藏储层中,储集层渗透率随地层压力下降而急剧降低,渗透率变化系数是重要的特性参数。本文研究了异常高压油藏稳定渗流规律,建立了利用系统试井资料求取渗透率变化系数的方法。
In overpressure reservoirs,the permeability of reservoir rapidly decreases with the formation pressure decreasing and the permeability variation coefficient is important characteristic parameter.The paper studied stable seepage flow rule of overpressure reservoir and created the method for using systematic well testing data to compute permeability variation coefficient.
