Acoustic telemetry systems and methods with surface noise cancellation |
摘要 |
<p>Acoustic telemetry systems and methods with surface noise cancellation. One illustrative embodiment may include an acoustic telemetry system comprising a transmitter (28) configured to generate an acoustic information signal that propagates along a drillstring (8), and a receiver (200) configured to detect an acoustic receive signal from the drillstring and a noise signal from a surface environment. The receiver operates on the acoustic receive signal and the noise signal to produce a modified signal indicative of the acoustic information signal and having a reduced noise content relative to the acoustic receive signal.</p> |
