Acoustic communication apparatus for use with downhole tools

摘要

Acoustic communication apparatus for use with downhole tools are described. An example acoustic communication apparatus for use in a wellbore includes a first acoustic transducer to generate first acoustic signals. The first acoustic transducer is mounted in an interior of a first drill collar to transmit the first acoustic signals via at least a portion of a body of a drillstring or a mud channel within the drillstring to a second drill collar. Additionally, the example acoustic communication apparatus includes a first receiver mounted to the first drill collar to receive second acoustic signals transmitted from the second drill collar.
