Research On Distributed Remote Monitoring System For Pumping Unit

With the rapid development of the oil industry, the traditional management way can’t satisfy the modern requirements of well oil production. In order to increase oil production, reduce labor intensity, reduce production costs, increase productivity and oilfield automation management, distributed remote monitoring is the trendA distributed remote monitoring system,which mainly composed of data collection terminals, telecommunications network, Personal Computer-side monitoring software, database server, Web server and Web browsers, have been proposed to solve the problems of traditional management way。Operating condition of oil machine has been collected by data collection terminals and network digital video camera in real time, and GPRS wireless transmission technology and the Internet technology have been adopted to transfer the data to the PC monitoring software and database server for the purpose of remote real-time monitoring;Through database paging and database query caching technology,Web server and Web browsers based on Browser/Server structure have been constructed to allow Web browsers access to Web server to get real-time data and historical data from the database server; ActiveX technology has been adopted to realize the preview of and the storage of real-time video.In this way, the problems of the remote real-time monitoring and control of distributed oil machines by both the PC-side monitoring software and Web browsers have been effectively solved, and the automation of the management level pumping has been greatly improved.The effectiveness、safety and reliability of the distributed remote monitoring system has been verified by the stable running on well site in oilfield, meanwhile, work efficiency and the cost of production have been greatly improved.
