CASING THICKNESS MEASUREMENT USING ACOUSTIC WAVE CORRELATION

摘要

Systems, methods, and software for determining a thickness of a well casing are described. In some aspects, the thickness of the well casing is determined based on results of comparing a measured waveform and model waveforms. The measured waveform and model waveforms are generated based on operating an acoustic transmitter and an acoustic receiver within a wellbore comprising the well casing.

1. A method comprising:
accessing a measured waveform associated with an acoustic signal returned via a well casing based on operating an acoustic transmitter and an acoustic receiver within a wellbore comprising the well casing; comparing the measured waveform to a plurality of model waveforms, wherein each of the plurality of model waveforms corresponds to a different thickness of the well casing; and determining, by operation of data processing apparatus, a thickness of the well casing based on results of comparing the measured waveform and the plurality of model waveforms.
