Abstract: It introduced correlation leak detection technology and then analyzing the theory of correlation leak detection on mathematics. Then gave a method that differentiates and analyses a signal interference like leak by using different apparatus. By this method, can improve the reliability. Finally, introduces the process of combination detection of a leak on pipeline.
Key words: correlation detection; signal interference; reliability; combination detection of leak
