With respect to those traditional electromechanical sensors the optical fiber sensor system offers small volume, high sensitivity, immunity of corrosion and electromagnetic interference. It is feasible to build permanent distributed sensor systems based on optical fiber sensing technologies, which can monitor the analytes online and in time. Optical fiber sensing technologies are widely developed and used in oilfield today. The optical fiber technologies used to monitor the temperature, pressure, seism, flow field and stress in the oilfield are introduced in this paper. Research achievements of each technology home and abroad are illustrated. The merits of these technologies are described, and the development trends of them are also proposed.
