Paper Abstract
In the field of oil well logging, real-time monitoring of fluid flow parameter provides a scientific basis for oil and gas optimization exploration and increase of reservoir recovery, so the non-intrusive flow test method based on turbulent vibration is proposed. The specific length of sensor fiber wound tightly around the outer wall of the pipe is connected with the optical fiber gratings at both ends, the sensor fiber and the optical fiber gratings compose the flow sensing unit. The dynamic pressure is generated by the turbulence when fluid flows through the pipe, and the dynamic pressure results in the light phase shift of the sensor fiber. The phase information is demodulated by fiber optic interferometer technology, time division multiplexing technology and Phase Generated Carrier modulation and demodulation techniques. The quadratic curve relationship between phase change and flow rate is found by experimental data analysis, and the experiment confirms the feasibility of optical fiber flow test method with non-intrusive and implements the realtime monitoring of flow.
