渗透率的理论计算方法

目前，没有一种直接的渗透率计算方法，测井数据输出的渗透率均为统计方法所得，不但误差大，而且区域局限性也强，给测井解释带来很大困难。本文试图寻找一种理论性强，适应范围广的渗透率计算方法。经与岩心分析资料对比表明，文中所提理论模型十分逼近理论模型十分逼近实际情况，具有很好的实用性。

Theoretical Calculation Method of Permeability

At present, there is no direct way to acquire accurate formation permeability. The permeability obtained from log interpretation is determined by statistic method, which has not only great errors but also is limited by different regions, therefore causing many difficulties in log interpretation. Comparison with core analysis data shows that the resulted permeability from theoretical model discussed herein is quite proximate to true formation permeability, so it is very practical.
