Design of the monitoring system for an ocean drilling rig

摘要

With the advantages of reasonable structure, convenient installation and easy transportation, the module drilling rig instead of the traditional oil rig, has been more widely used in offshore oil fields. However, due to its module design, there are still some problems such as low-level of automation and difficulties of monitoring and management of the whole system. In this paper, a supervisory control and data acquisition (SCADA) system for WZ11-4N WHPB oil platform is designed according to the demand analysis. The system hardware includes master computers, slave computers and a communication network. The software is involved with the design of data management system, control program and the monitoring system. Construction of the SCADA system should achieve real-time monitoring and data sharing of drilling data resources. It should effectively improve the control level and system efficiency, also facilitate control experts to analyze and process the data, and then provide effective service and security for oil exploration.
