Transducer for acoustic logging

摘要: An acoustic logging apparatus includes a tool body and housing. A transducer operating in the bending mode is mounted The operates such that it excited by or emits energy only one of two directions substantially perpendicular to face transducer. housing removed from axis body. receiver an outer sleeve having flange hat slidably within sleeve. sliding compensates for variations pressure temperature. transmitter main supported Combinations air gaps o-rings acoustically isolate piezoelectric crystal its enclosure. are configured be replaced field.
