Research On Applying Distributed Monitoring And Control Systems For Oilfield Production Process

In this paper the application of distributed monitoring and control systems for oilfield production is discussed from the instance of oilfield combine station distributed monitoring and control system. After introducing the research actuality and development of distribute control system, author analyzes the trend of distribute control system, pointing out the popularity applied DCS will progress to field-bus control system gradually. Both will coexist in a period of time and integrate each other in structure. With the Ethernet and Internet starting be applied in industry control, distributing control system will have better prospect in future. In the meantime, author analyzes the techniques in monitoring software developing such as dynamic data exchange, component development and OPC, discusses the realizing technique of remote monitoring system. At last, author describes the hardware design and software design of a distributing monitoring system in henna weigang oilfield combine station.Oilfield combine station plays a vital role in oilfield producing. Besides including several craftworks, it takes on disposal of oil, gas and water, oil storage and transportation etc important tasks. However, most oilfield combine stations have many problems such as technique behind the times in parameters measurement and control equipment, facility aging etc. These problems affect the producing safe badly. So developing the oilfield combine station producing real-time monitoring system has high practicality signification.The oilfield combine station monitoring system introduced in this paper adopted distributing structure, realized data monitoring and process controlling implemented by the PLC system, realized data displaying, MMI, supervising of whole craftwork and control system and report forms printing implemented by IPC. In the basis of the above system, established the remote monitoring system, realized remote monitoring and managing of real-time producing information. Having friendly MMI, good flexibility and high reliability, the whole system is worth to popularize.
