本文主要介绍利用斯通利波的频率偏移和时间延迟判断储层渗透性。
The paper mainly introduces the process of estimating the reservoir permeability using the frecquency offset and time lag of Stoneley wave.
当泥饼层较厚时，用斯通利波幅度衰减估算的地层渗透率及提取的横波时差是错误的结果。
When mud cake is thick, formation permeability and shear wave slowness evaluated from the attenuation of the amplitude of Stoneley wave are wrong.
结果表明，这两种声源激发的频散波具有很强的可对比性，它们的最低模式在单极声源激发时是斯通利波，在偶极声源激发时是弯曲波；
The results show that the dispersive wave excited by these two acoustic sources have strong contrast, which are Stoneley wave for monopole and flexural wave for dipole in the lowest mode.
