Abstract: Monopole transducer is a commonly used detector in acoustic logging instruments, and its per-
formance directly affects the data quality of acoustic logging. Through numerical simulation to establish the
model of “water-transmissive window-piezoelectric ceramic tube-oil cavity-skeleton”, the vibration and radi-
ation characteristics of the detector under the multi-physical field coupling are calculated, and the effects of
different structural parameters on the acoustic performance of the detector are investigated to obtain the better
transducer dimensions and more suitable transmissive window material. The results show that the acoustic
performance of the detector is greatly affected by the changes of the thickness and inner diameter of the piezo-
electric ceramic tube, and is insensitive to the changes of the height of the piezoelectric ceramic tube; increasing
the volume of the inner oil cavity within a certain range can improve the sensitivity of the detector; the glass
fiber reinforced plastic (FRP) with a thickness of 2 mm has great acoustic transmittance, and also possesses
certain mechanical properties, which is an appropriate choice for the detector’s acoustic window. The research
has a guiding significance for the optimization of monopole acoustic logging detectors.
