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 using flow-induced pipe vibration is proposed, and fluid flow is measured non-intrusively, the study is conducted on vibration induced by turbulent flow when fluid flow through pipe. The frequency characteristics of the pipe´s vibration signals is found,then the fixed relationship between standard deviation of pipe wall´s vibration induced by fully developed turbulence and mean flow rate is determined.
