Numerical analyses on the sandwich dipole logging transducer with various loads

Numerical modeling for a sandwich dipole well logging transmitting transducer is conducted in this work. The characteristics for the first-order bending vibration of the sandwich transducer within different fluid loads are numerically analyzed. It is found that the resonant frequency and transmitting voltage response level are affected by the density, acoustic velocity and acoustic impedance of the fluid load. The numerical results were preliminarily validated by our experiment. The numerical analyses may provide useful suggestion for both the simulation design of logging transducer and the acoustic logging applications.
