Abstract: Recently, with the rapid improvement of Chinese economy and people's living standards, the demand for the exploitation and transportation of energy is continuously increasing. As one of the important transportation modes, the length of petroleum and gas pipelines in China has increased greatly. Pipeline leakage detection technology is one of the basis for efficient and safe pipeline transportation. This article firstly introduces the development history and existing research achievements of pipeline leakage detection and location technology, and analyzes various common methods. Secondly, the fundamentals and operation manners of numerous routine pipeline leakage detection approaches are described. Then, based on the actual industrial situation, the characteristics and application scenarios of each detection method are described. At last this article analyzes the challenges of the mentioned detection technologies, and looks forward to the development direction of pipeline leak detection technology.

Key words: pipeline transportation; , leakage detection; , leakage location
