The acoustic method for assessing the quality of casing cementing is currently one of the most accurate and affordable assessment methods. Acoustic logging is based on the excitation in a fluid filling a well of a pulse of elastic vibrations and registration of waves transmitted through a cement stone at a given distance from the emitter at one or more points on the axis of the well. The article discusses the main errors that can be made during the acoustic logging, the possible causes of unsatisfactory readings and provides recommendations for further work.
