Thus, when the permeabilityof 50% probability and the coefficientofvariation for lognormal distribution are known, one can establish a definite numerical model of permeability plane distribution.
这样，知道模型的渗透率对数正态分布概率50%处渗透率和变异系数，就可以建立起确切的渗透率平面模型。

The paper studied stable seepage flow rule of overpressure reservoir and created the method for using systematic well testing data to compute permeabilityvariationcoefficient.
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。

Furthermore, the variation laws of the pore water pressures and the permeabilitycoefficient during the consolidation of the refuses are analysed.
