Recently, the perforation leakage accidents of gas pipeline which caused by corrosion occur frequently, and bring great economic losses, So itis particularly important to located the leakage of the buried gas pipeline in order to take measures to reduce the potential unsafe factors, immediately ,and nip in the bud. In this article,
the constraint space model of geological environment where buried gas pipeline located was firstly constructed, and implemented three-dimensional testing and real-time monitoring; then referenced to the back-calculation methods of the sources intensity theory to accurately predict or determine the leakage point and improve the pipeline operating efficiency .
KEYWORDS
Source Intensity; Back-Calculation Methods; Pipeline Leak-Detecting; TechnologyINTRODUCTION
Currently, the world's major pipelines reached more than 230 million kilometers, 150 million kilometers natural gas pipeline, while the pace of development in China pipeline industry and technology has entered the advanced ranks of world’s (Luo & Zhao, 2007).Along with the ncrease of the line and the growth of pipe age,
occurrence of pipe leakage accidents occur frequently due to construction defects, corrosion and third-party damage. Therefore, the accuracy of pipeline leak detection
