VIBRATION MEASUREMENT SYSTEM WITH REFLECTOMETRY AND RELATED METHOD FOR THE CONTROL OF MULTIPHASE FLOWS

Abstract

A vibration measurement system for monitoring multiphase flows in production wells or pipelines using multimode fibers, comprising: - a multimode optical sensing fiber - an optical source with at least one fiber output port, which generates optical pulses to be sent to the sensing fiber - an optical receiver with at least one multimode fiber input port - an optical device with at least 3 multimode fiber ports, in which one port is connected to the optical source, one port to the optical receiver, and one port to the multimode sensing fiber - a system for processing the output signals from the optical receiver, further comprising more than one spatial mode filter. A process for reconfiguring an optical reflectometry system already installed in a control structure is also described.
