Beschreibung
Zusammenfassung:	The utility model discloses a logging-while-drilling acoustic logging sound isolation device, which comprises a drill collar for installing emitting and receiving probes, wherein the drill collar is provided with a plurality of sound isolation grooves for isolating drill collar mode waves or structural sound waves; and the sound isolation grooves are annularly and uniformly formed on the drill collar. The logging-while-drilling acoustic logging sound isolation device has a simple structure, a reasonable design, a good sound isolation effect and high mechanical strength, drill collar waves or structural sound waves can be isolated effectively, and the requirement of a drilling project on the rigidity of a drill stem system in the logging-while-drilling process can be met.
