Abstract

Abstract: In order to improve the monitoring efficiency and reliability of oil and gas pipeline, the monitoring method of petroleum pipeline temperature based on singleended Brillouin optical time domain analysis has been proposed. The temperature experiment at oil and gas pipelines leakage location has been taken. The experiment results show that distributed optical fiber sensing technology based on Brillouin scattering can accurately monitor and identify the pipeline temperature change. The temperature measurement resolution can reach 3 ℃ and spatial resolution of 1 meter in 25 km sensing fiber.
