Abstract: To overcome the limitations of narrow bandwidth and low sensitivity of Pb-based Lanthanum-doped Zirconate Titanates（PZT ）piezoelectric transducers used in ultrasonic imaging logging, PZT-5A piezoelectric ceramic was used as the piezoelectric component and epoxy resin as the polymer component. The influence of the piezoelectric phase component percentage on the equivalent performance parameters of 1-3 piezocomposites was theoretically analyzed. The harmonic response characteristics of transducers with different structural dimensions were analyzed through simulation. Based on the results, the parameters of the 1-3 piezocomposite ultrasonic logging transducer were finalized, and its harmonic and pulse response characteristics were tested experimentally. The results show that the transducer has a center frequency of 319.82 kHz, a relative pulse-echo sensitivity of −26.64 dB, a pulse width of 6.67 μs, and a −3 dB relative bandwidth of 50.38%. The transducer can effectively excite the thickness vibration mode, generating pulse echoes with large amplitude and narrow pulse width. These findings demonstrate that the proposed ultrasonic logging transducer exhibits high sensitivity and a wide bandwidth, effectively extending the operational frequency range and improving imaging quality in complex logging environments. It holds significant application value for upgrading existing tools and developing new-generation equipment for ultrasonic imaging logging.
