Abstract：Inorder tosolve theproblems oflow accuracyand insufficientrobustness of leakage identificationin traditional oil and gasstorage and transportation，a leakage identification method based on improved signal noise reduction and timedelay estimation is proposed.Firstly，theparametersof variational mode decompositionare optimized by adaptive particle swarm optimization algorithm to improve the noise reduction processing abilityof leakage signal.Then，the dynamic exponential parameter，coherence factorand proportional coeficient are introduced to improve the phase transformation weighting algorithm to enhance the delay estimation accuracyofthe algorithm underlow SNR conditions.The results show that the positioning eror ranges of the fixed leakage point and the random leakage point are 0.432～1.305 m and O.137～1.204 m，respectively，and the average positioning error is less than O.84 m. It is concluded that the method has high positioning accuracy and strong robustness，which can provide ahigher precision solution foroil andgas storageand transportation leakage，and has certainsignificance for ensuring the safety of oil and gas storage and transportation.
