CASING PIPE DAMAGE DETECTION METHOD BASED ON ELASTIC WAVE

摘要：

The elastic wave reflections which take place at the fixed or free end of uniform medium may be considered as special cases of the general reflection and refraction phenomena occurring at any discontinuity in the medium properties. In this paper, the medium is a long steel casing pipe connected with many short pipes. On the basis of elastic wave reflection and refraction theory in well-proportioned medium, identifying the time difference of the acceleration waveforms in the steel pipes recorded damage location can be detected.
