摘　　要：朱云生，胡澍．应用低频斯通利波衰减评价地层渗透率．测井技术，１９９５，１９（６）：４１６～４２０本文提出了一种简单、实用的地层渗透率解释方法。该方法把由声波测井数据得到的斯通利波衰减分为介质内衰减和孔隙流体渗流衰减两部分。解释时，先确定介质内衰减，然后由渗流衰减确定地层渗透率。对模拟的声波测井数据的处理结果表明，这是一个有效的方法。A simple and practical method for evaluating formation permeability this proposed in is paper. In this method, Stoneley wave attenuation from AC log is divided into two parts: attenuation through porous media and percolation attenuation through pore-fluid. In log interpretation, medium internal attenuation is first determined, and then formation permeability is determined by the percolation attenuation directly. The processing results of the simulated AC logging data show that this method is good and successful.
