油气田安全信息系统设计

摘要
油气田信息系统应用节点数量多且位置分散,各个节点需要处理大量数据,节点间又需要稳定、安全的共享数据。为解决这种状况,系统采用分布式数据库技术实现。介绍了其的特点和基本原理,归纳了高含硫油气田安全信息系统的数据特点和需求,然后从配置数据库访问方式、建立数据库链接、优化数据查询等方面详细阐述分布式数据库技术在高含硫油气田信息系统中的设计和实现过程。通过实践的验证,有效地解决了数据分散、相互共享和集中管理的矛盾,对解决远程数据管理系统具有一定的借鉴意义。
In the gas well information system,the number of application node is large and its position is distributed,every application node need to deal with large data and share data stably and safely between each other.Technology of distributed database is used in order to solve the problem.Introduces its characteristic and basic principle at first,concludes the characteristic and requirement of data in the high-sulfur gas well safety information system,and then expatiates the design and realizing process of distributed database technology in the high-sulfur gas well information system by configuring database access mode,setting up database link,optimizing database query.After checking by practice,the method can solve the contradiction of distributed data,share each other and concentrated management in effect,and supply a little reference to solve the remote database management system.
