[Abstract]:The emergence and use of deepwater drilling platforms have successfully realized the exploitation of rich marine oil and gas resources and effectively alleviated the energy crisis caused by the scarcity of land resources. However, because the deepwater drilling platform is far from the land operation, the sea conditions are changeable, the whole platform is huge and complex, so it is very important to monitor the whole drilling platform in real time to ensure its safe and efficient operation. This paper mainly studies the related technologies used in constructing the integrated monitoring system of deepwater drilling platform. Using the field bus technology, the LabVIEW software KEPserverEX and Siemens PLC are used to complete the construction and operation of the integrated monitoring system and realize the monitoring function of the system. The main works are as follows: (1) the most advanced deep-water drilling platform, the sixth generation semi-submersible drilling platform, is studied, and its structure, composition and characteristics are introduced. Combined with the characteristics of drilling platform, the design requirements and functions of the integrated monitoring system are analyzed, and the design ideas from two aspects of software and hardware are described. (2) the network structure of the integrated monitoring system is designed and the network structure of the integrated monitoring system is designed, which includes the field equipment layer. Monitoring layer, application layer three-tier network structure. Finally, it is decided that the three-layer network uses Profibus fieldbus, ring redundant industrial Ethernet and commercial Ethernet respectively. In addition, a wireless local area network is constructed as a supplement to the wired network. So that the staff can monitor the platform parameters through mobile terminals at any time and anywhere. (3) after the overall design of the monitoring software and the specific network structure are determined, the ballast and drilling on the drilling platform are separately, The three subsystems are summarized from general situation, characteristics to main monitoring parameter data. The control logic relationship among the parameters of each subsystem is studied to achieve the purpose of operating the control equipment of the monitoring software. (4) based on LabVIEW, the monitoring interface module, curve module, alarm module and data query module of the upper computer client are developed and designed. Using KEPserverEX as the OPC server to connect the host computer with Siemens S7-300PLC as the lower computer, the function of each module is realized. (5) the design and implementation of the wireless local area network on the drilling platform is studied, and the composition of the wireless network is discussed. The configuration and communication strategy to the development of mobile monitoring terminal equipment program are designed, and the application program testing is completed. The data function of wireless monitoring platform is realized.
