Study on the research for the oil well detection system

本文介绍了一种基于Mach-Zehnder光纤干涉仪原理的油井远程监控系统。该系统可以实时检测油井周围有无异常情况的发生。本文分析了该技术的工作原理,讨论了在振动信号作用下光纤中传播的光波相位变化关系。为了对周围采集来的振动信号做实时处理,设计了一种基于DSP系统的数据采集处理系统,该系统具有抗干扰能力好、实时性强、可靠性高、功耗低等优点。

A new distributed optical fiber sensing technology based on the principle of Mach-Zehnder optical fiber interferometer is introduced in this paper. This technology can be used to detect the abnormal signal around the oil well in real-time. The principle of this technology is analyzed, and the phase changes because of the action of acoustic wave of the signal of the vibration. In order to process the signal of the vibration in real-time, a kind of data acquisition and processing method based on DSP system is presented. The system has some advantages such as better anti-jamming, good real-time performance, high reliability, low-power dissipation and etc.
