Abstract

Modern oil production in the oilfield management needs a sensor which enable fast, reliable and cost-effective through highly integrated optical measurement systems. A sensor for accurate and long-term fluid high pressure and temperature monitoring in oil down-hole based on optical fiber Bragg grating is presented. This sensor, using fiber Bragg grating written in side-hole single mode fiber, has small size and simple construct. At different temperature, the pressure measurements from atmospheric pressure to 40 Mpa has been made. It has very linear relationship between peak separation and pressure.
