一种基于BOTDA的分布式输油管线泄露检测技术
Technology of distributed pipeline leak detection based on BOTDA
摘要
Abstract
We designed a kind of strain sensing cable based on sensitive material of crude oil by the requirement of small-scale pipeline and high-precision leak detection, and also the response model of the brillouin frequency shift of local strain on the fiber optical cable was proposed to discover and locate the leak event. In the formed simulation system, we located the small-scale oil leak accurately within 15 minutes by the distributed detection of brillouin frequency shift caused by oil leak using BOTDA, besides, the spatial resolution of 1m and the positioning error of 0.lm in the length of 1.714km were realized.关键词
