TRANSDUCER ASSEMBLIES FOR DOWNHOLE TOOLS

摘要

Methods and related systems are described relating to a sealed acoustic transducer assembly for use in a wellbore is provided. One or more acoustic transducer elements, which can be receivers or transmitters, are housed in an elongated fluid filled sealed container. The sealed container is adapted to be removeably mounted to a portion of a drill collar. The container, which for example can be made of thin corrugated metal or rubber, includes flexible portions along the length of the container which allows for volume changes when exposed to changes in external pressure and/or temperature.
