ABSTRACT:
The acoustic detector in a mud pulse telemetry system includes a one dimensional waveguide disposed between a pressure transducer and a conduit carrying drilling fluid to a drill string. The waveguide, which may include a flexible hydraulic hose, increases the amplitude of the acoustic mud pulse signal received at the transducer located at the termination end by a factor of two or more. In addition, the waveguide may be substantially filled with a fluid having a viscosity higher than the viscosity of the drilling fluid so as to provide a means to dampen high frequency noise, and thereby improve the signal-to-noise ratio at the pressure transducer.
