Abstract
Description
technical field
[0001] The invention relates to a method and device for identifying leakage events of natural gas pipelines with optical fiber sensing, and relates to the technical fields of mechanical vibration measurement, impact measurement and pipeline systems. Background technique
[0002] At present, the total length of pipelines built in the world has reached 2.5 million kilometers, which has surpassed the total mileage of railways and has become the main mode of energy transportation in the world. Oil transportation in developed countries and oil-producing regions in the Middle East has all realized pipelines. my country's pipelines have also developed rapidly in recent years, with a total length of more than 70,000 kilometers. A large energy pipeline network has initially formed across the east, west, north and south, covering the whole country, and connecting overseas. Pipeline transportation has become the deployment of strategic energy such as oil and gas. The mai...
