| Zusammenfassung: | A drill string telemetry system comprises an acoustic reflector mounted to the surface end of the drill string. The reflector is adapted to reflect surface-generated torsional acoustic noise away from the drill string. The reflector attenuates the power of 500 Hz torsional acoustic noise power impinging on the reflector by a factor of at least 2. |
