Method of detecting signals in acoustic drill string telemetry |
摘要 |
A method of acoustic telemetry in a drill string in a wellbore, comprises; transmitting an acoustic signal related to a parameter of interest from a transmitting location into the drill string; detecting signals propagated through the drill string at a receiving location, where the detected signals including noise; determining a drill string transfer matrix defining the propagation of signals through a transfer interval between the receiving location and the transmitting location; and using the detected signals and the drill string transfer matrix for obtaining an estimate of the acoustic signal.
