| 摘 要： | 讨论了在软地层中声波测井的波形特点,重点介绍了一系列不同软地层中横波和弯曲波的波形和特点,说明在软地层井中应当用偶极声源激发的弯曲波估计地层的横波速度,同时也详细介绍了软地层斯通利波的波形和频散特性,强调它的速度与硬地层大不相同. |
| 关 键 词： | 声波测井 纵波 横波 斯通利波 |

| Abstract: | Wave form characters of sonic logging in soft formation are discussed. Wave form and characteristics of shear wave and flexural wave in different soft formations are studied. The flexural wave induced by dipolar sound source would be used to estimate shear wave velocity in soft formation wells. At the same time, the wave form and dispersion characteristics of Stoneley wave in soft formation are introduced in detail, its velocity is more different from that in hard formation. |
| Keywords: | sonic logging compressional wave shear wave Stoneley wave |
