Application research of distributed optical fiber Raman temperature sensor in the security of oil depot

Research and application of distributed optical fiber Raman temperature sensor (DTS) is briefly introduced in this paper. The current situation of domestic oil, gas storage and transportation security is analyzed. In the instance of the application in the project of Rizhao Port oil tank area, a field test is conducted. The experimental results show that the various points' temperature that depot tanks and transmission lines possess can be measured in a real-time online way by distributed optical fiber Raman temperature sensor and the temperature points' location can be pinpointed. Due to these functions, oil depot fire caused by high temperature can be prevented effectively. In the Engineering Application, there are some important parameters that sensing fiber length is 30 km, the spatial resolution is 2 meters, and the temperature of uncertainty is 1 Celsius degree.
