Abstract: Leakage accidents in oil pipeline transportation occur frequently in recent years.In order to guarantee the pipelines work safely and minimize the losses caused by leakage accidents,it is necessary to study leakage detecting technology to raise the sensitivity of leakage detection and accuracy of localization.Allowed to oil pipeline characteristics,analyze the principle of dynamic pressure wave leak detection technology and the key factors to influence accurate positioning.Taking account of the corresponding characteristic of the signal singularity and wavelet transform module maximum in multi-scale changing,the wavelet transform is applied to get the featured inflection point of pressure wave.As a result,the dynamic response time diversity between pressure sensors will be more precise,accuracy of localization to oil pipeline will be more improved.
