Brillouin optical time domain analyzer BOTDA and distributed acoustic sensors DAS are two kinds of advanced OTDR-type distributed optical fiber sensors,which can achieve 50 to 100 kilometers measuring distance. The measuring principle and technical advantages of these two sensors were given. The application of oil and gas pipelines online leakage,the third-party damage and geological disasters monitoring based on the sensors as well as the successful application cases at home and aborad were desribed. The analysis and cases indicate that BOTDA and DAS can obtain multi-parameter measurements and multi-event positioning,thus ensuring long-distance oil and gas pipelines safe.
