Multiple transducer MWD surface signal processing

摘要

A system and method for signal processing are disclosed. One problem in measurement-while-drilling systems including a downhole acoustic transmitter is the presence of uphole generated noise and reflected signals. By proper spacing and timing of multiple transducers and measurements, the present invention filters from the received, corrupted signal the uphole noise and reflected signals. Thus, a more accurate depiction of the transmitted signal is generated uphole.
