| 摘 要： | 以渗透性地层的测井声波传播理论为基础,研究斯通利波反演地层渗透率方法。斯通利波计算渗透率的关键在于如何将其受渗透率的影响因素与其它影响因素分离开来。已采用的计算方法有相速度(或慢度)方法、衰减幅度方法;作者使用的方法是结合相位滞后和衰减变化的测量来计算渗透率。求取渗透率过程有波场分离、正演模拟和渗透率的反演计算3个主要步骤。

| Abstract: | With the theory of the logging acoustic wave propagation in permeability formation,as the basis to study inversion method of permeability using Stoneley wave.The key of algorithm for permeability from Stoneley is how to calculate permeability by the permeability of its factors and other factors separate.The algorithm methods have been used with velocity(or slowness) method,the amplitude attenuation method,and a relatively new rapid method,combined with the phase lag and attenuation measurements to calculate... |
