Guided wave attenuation well logging excitation optimizer based on waveform modeling

摘要

Methods and apparatus for inspecting oilfield infrastructure components. Methods include estimating an optimal value for at least one excitation parameter for an acoustic excitation source to produce a guided wave of mixed multiple modes in the component; selecting at least one excitation parameter corresponding to an optimal simulated guided wave determined in dependence upon the application of waveform criteria to the time domain waveforms; and generating a guided wave in the tubular using the at least one optimal excitation parameter. Methods may include calculating a guided wave dispersion relation; modeling each of the plurality of simulated guided waves, wherein the modeling comprises generating a time domain waveform for each of a plurality of wave modes in dependence upon the acoustic excitation source; selecting the at least one excitation parameter corresponding to an optimal simulated guided wave determined in dependence upon the application of waveform criteria to the time domain waveforms.
