随着海洋油气田自动化生产程度的逐步提高，跨平台联控的工况越来越普遍。如何针对实际需求，选择安全可靠、成本经济的数据通信方式也成为了实施过程中的关键因素。通过南海某油田群新建平台与老平台之间的OPC通信实例，分析了OPC通信的技术特点，重点阐述了OPC通信的系统配置及软件应用方法，以期对同类工程有一定的启发作用。

With the gradual improvement of automatic production in offshore oil and gas fields, cross-platform joint control is becoming more and more common. Choosing a safe, reliable and cost-effective data communication mode has become a key factor in the implementation process. The technical characteristics of OPC communication are analyzed through an example of OPC communication between a newly built platform and an old platform in a certain oilfield group of the South China Sea. The system configuration and software application methods of OPC communication are mainly expounded, so as to provide some reference for similar projects.
