The invention discloses a pipeline leakage positioning method for multiple noise reduction so as to improve pipeline leakage positioning precision. The method comprises the steps that firstly, collected pipeline leakage signals are subjected to CELMD decomposition to obtain a series of PF components and residual components; then the correlation coefficient of each PF component is calculated to perform noise reduction processing through the correlation coefficient criterion, and the effective PF component is initially screened; then the maximum correlation kurtosis deconvolution (MCKD) principle is used to perform secondary noise reduction on the initially screened PF components, and the PF components are selected; and finally, the PF components subjected to secondary screening are subjected to signal reconstruction, and the time delay of the leakage signals is calculated through cross-correlation to complete pipeline leakage positioning. By means of the pipeline leakage positioning method, the problems that when an existing method is used for processing pipeline leakage signals, the noise interference is difficult to extract, and positioning is inaccurate are solved, and a new method is provided for pipeline leakage detection.
