Overview

Research demonstrates enhanced dual-frequency outputs in an acoustic transducer, suggesting improved logging efficiency while drilling.

Key Points

  • The research aims to develop a dual-frequency impedance matching method for an acoustic transducer to improve output efficiency.
  • Utilized a multi-mode equivalent circuit model of the transducer.
  • Incorporated a compression factor to improve convergence.
  • Employed an improved particle swarm optimization algorithm for parameter calculation.
  • Tested the impedance matching network in monopole and quadrupole modes.
  • Achieved a 1.5 times broader frequency band and a 1.9 times enhancement in active power.
  • Enhanced transmitting voltage response by 21% at 4.5 kHz and 12% at 14 kHz.
  • Improved maximum horizontal directivity by 32.34 dB for monopole and 43.18 dB for quadrupole mode.
  • Concentrated main energy of the excitation signal post-impedance matching.
