ACOUSTIC FREQUENCY SELECTION IN ACOUSTIC LOGGING TOOLS |
| 摘要 |
A logging system has a sonde in a borehole, which transmits sonic waves with one or more dipole sources to optimally excite dipole flexural mode sonic waves in the borehole. The system first determines the Airy frequency of the borehole. Then, the dipole sources are fired at a dipole firing frequency selected based on the Airy frequency. |
