Paper Abstract

In the oil field development and production, fluid flow is an extremely important parameter which determines the transmission characteristics of the oil production, real-time monitoring of fluid flow parameter provides a scientific basis for oil and gas optimization exploration and increase of reservoir recovery. A method for interrogating fiber optic sensors non-intrusively sensing fluid flow is proposed, those sensors are positioned between pairs of low reflectivity fiber Bragg gratings, the fiber optic sensors wrapped closely around the outside wall of pipe are used to sense the internal information of fluid flow, new optical fiber monitoring system of fluid flow bases on optical signals. When optical signals are transported in optical fibers, phase is changed due to the effects of the fluid flow , the size of which can be determined by measuring the relative changes of the phase. So the optical fiber monitoring system of fluid flow making use of modulation and demodulation techniques of phase generated carrier accurately determines the size of fluid flow with non-intrusion.
