What is it about?
Determining the location of the leakage layer is the premise of plugging the leakage during drilling. The comparison of de-noising effect of pressure wave signal and the analysis of transient pressure wave leakage detection model based on cepstrum are established.

Why is it important?
The pressure wave signal of imf is reconstructed by EMD, EEMD and CEEMDAN algorithms. All the three methods can effectively suppress the interference noise, and CEEMDAN has the highest reconstruction accuracy.
Perspectives
Transient pressure wave analysis method based on cepstrum is the core technology of leakage detection method in this paper. It is hoped to provide theoretical and technical reference for leakage detection technology.
