光纤传感技术在油田监测领域中的应用

Application of Optical Fiber Sensing Technology in Oilfield Monitoring

光纤传感技术是以光波为信息载体,光纤为传输介质来感测外界物理量变化的技术。当光波在光纤中传输时,其功率、相位、波长、偏振态等参数会受外界环境影响而发生改变,通过检测光纤中传输的光波参数的变化,获得外界被测量的信息。本文阐述了光纤传感技术在的温度、压力、多相流、地震检波等油田领域中的应用及国内外现状,然后指出了光纤传感技术在油田应用中的巨大优势和广阔前景。

Optical fiber sensing technology is a technology that uses light wave as information carrier and optical fiber as transmission medium to sense changes in external physical quantities.When the light wave propagates in the optical fiber,its power,phase,wavelength,polarization state and other parameters will be changed by the external environment.By detecting the changes of the light wave parameters transmitted in the optical fiber,the information measured outside can be obtained.This paper describes the application of optical fiber sensing technology in oil fields such as temperature,pressure,multiphase flow,seismic detection and the current situation at home and abroad,and then points out the great advantages and broad prospects of optical fiber sensing technology in oil field application.
