分布式光纤传感器在数字油田应用中的研究进展

Research Progress of the Application of Distributed Optical Fiber Sensor in the Digital Oilfield

分布式光纤传感器根据其原理可以分为瑞利散射分布式光纤传感器,拉曼散射分布式光纤传感器以及布里渊散射分布式光纤传感器。分布式光纤传感器因具有测量范围宽,测距长,高灵敏度和高精度而得到广泛应用,但它在油田领域的一些应用却相对陌生。本文的目的在于阐述分布式光纤传感器在数字油田应用中的研究进展,反映国内外对这块领域研究的现状,分析各种分布式光纤传感技术的优缺点,以此使得其在数字油田中有更好的应用前景。

Distributed optical fiber sensors can be divided to Rayleigh Scattering distributed optical fiber sensors, Raman Scat-tering distributed optical fiber sensors and Brillouin Scattering distributed optical fiber sensors according to the principal. Distributed optical fiber sensors have been widely used because of the wide measuring range, long distance, high sensitivity and accuracy, but the applications in the oil fields is relatively unfamiliar. The research progress of the application of distributed optical fiber sensor in the digital oilfield is introduced to reflect the situation of domestic and international research. The advantages and disadvantages of distrib-uted optical fiber sensors are analyzed for the better application prospect in the digital oilfield.
