【摘要】 本文针对国内油田监控的现状，油井监测大多还是由人工每日定时检查设备运行情况并测量、统计采油数据，但是由于油井数量多且分布范围广，这种方式必然使工人劳动强度加重，而且影响了设备监控与采油数据的实时性，甚至准确性等问题，提出了主从站并存的监控方法，采用MODBUS通信协议，对远程油井，系统使用GSM的SMS实现数据采集与监控；对短程集中分布油井，系统通过RS232／RS485／无线传输网络，采用C／S结构实现数据采集与监控。在Delphi6.0语言平台上，进行了监控服务器系统的开发，设计出监控系统界面、完成了MODBUS协议在有线网络上的实现以及在无线模块与SMS的无线通信中的实现、监控数据的历史查询与统计分析。以及现场终端监控单元的各项控制功能与任务实现，规划出系统的其它通信接口，以兼容其它系统及多种仪表，同时在终端单元按时间保存采集的功能数据，供服务器系统查询与现场检测需要。进行了抽油机监控中最重要的空抽判断与空闲决定的策略研究。通过实际应用数据分析，取得了比较满意的经济效益，在系统通信功能上有一定的突破，达到了对油田节能降耗、挖潜增效的目的。 我们提出通过成熟的GSM短信息的方式用于油田监控系统的远程通信技术，在国内还是首例，现场测试表明其运行结果还是比较满意的，在我国低渗、低能藏的油田自动化系统建设上具有很高的推广价值。更多还原

【Abstract】 Based on status ouo of supervisory control system, we put forward a new supervisory control irethod, where the principal and subordinate coexists at station. Adopting MODBUS communications protocol, the system realizes data acquisition and supervisory control to long-distance oil well using GSM SMS. To short-haul but convergence distributing oil well, the system adopts C/S framework via RS232 or RS485 or wireless transmission network. We developed the sever system on Delphi6.0 platform: designing interface of supervisory control, realizing MODBUS protocol in wire network and wireless communication with SMS based on wireless module, implementing query and analyze on data of history. Our work also included implementing all functions to terminal unit, marking out other communication interface of system in order to be compatible to other systems and instruments. The system can also save function data of terminal unit on schedule to be queried by sever system and detected in local. At the same time it is important to do research on rules of empty pump and of idle decision. Through analyzing on actual data, we found the system does have economical benefit, attaining the purpose of reducing consume and increasing benefit. In communication function of system, a little breakthrough has also been made.We put forward communication technology of GSM SMS, which is the first time in domestic to be applied to long-distance communication of supervisory control system in oil well. The running result is relatively satisfied and the system has great value in oil field to automatic system construct in oil field of low-seep and low-storage.更多还原
