| 摘 要： | 本文在文献2]的基础上,进一步详细分析了裸眼井中点声源激发的弹性波的两种共振模式。分析表明:共振纵波与共振横波的振幅属同一数量级。同时论证了共振纵波与共振横波到达井轴上同一点的位相差等于零。本文的这两个结果为在实际声波测井工作中区别共振纵波与共振横波及进一步提取横波信息提供了依据。

| Abstract: | Based on reference2],two resonant modes of sound wave in a fluid-filled borehole in acoustic well logging are further analysed.It is shownthat,the amplitude of the longitudinal wave and that of the transversalwave are of the same order or magnitude and their phases when they ar-rive at the same point on the well axis are the same |
