ANALYSIS ON A NEW TYPE PIEZOELECTRIC TRANSMITTER WITH HIGH PERFORMANCE FOR ACOUSTIC LOGGING

摘要：

　　A new type transmitter with segmented tri-laminar structure is proposed in acoustic logging, especially in through bit acoustic logging.Numerical simulation is conducted using the finite element method.Vibrational modes shapes with resonant frequencies are displayed through mode analysis.Admittance characteristics and transmitting voltage responses are received by harmonic response analysis.The impact of piezoelectric rectangular column thickness and transducer width on transmitting voltage responses is calculated.Results show that the segmented transmitter has higher transmitting performance comparing with the traditional one under the same size.This work provides a theoretical basis for transducer optimization in acoustic logging, especially in through bit acoustic logging.
