网络化永久性油气藏远程动态实时监测系统设计

本文设计了一种应用于油气藏永久性实时动态监测系统。该系统用光纤Bragg光栅(FBG)传感器作为井下永久性传感器,测量目的层的温度、压力等参数的模拟信号;在井口建立数据采集处理系统,将模拟信号解调成数字信号;通过GPRS无线移动通信网络传输到监测中心的数据库服务器上,并以Web形式发布到Internet网络上,同时提供移动用户浏览接口,且当数据异常时可以发送报警短消息。该系统实现了油气藏的远程实时动态监测,可以为油藏管理人员和技术人员及时、准确地做出决策提供可靠依据。

Permanent remote dynamic real-time network monitoring system of oil/gas reservoir.

The paper designed permanent dynamic real-time monitoring system that is applied to oil/gas reservoir monitoring.The system uses fiber Bragg grating (FBG) sensor for permanent downhole sensor and to measure the analog signals of parameters such as temperature and pressure etc on the targets; the data acquisition and processing systems are built up at the uphole site,the analog signals are modulated to digital signals that are transmitted to the server of database in monitoring center through GPRS wireless mobile communication network and published on the Internet as Web form as well as provided simultaneously to browsed interface of mobile user,the alarm short notes can be sent out when anomalous data appear.The system realized remote real-time monitoring of oil/gas reservoir and provided reliable foundation for reservoir managers and technicians to make decisions correctly and timely.
