针对石油领域采油工程海量、分布、异构的数据源,在构建领域全局语义模型和实现全局语义查询的基础上,建立一套面向采油工程的基于领域本体的数据服务系统 OPODSS。提供基于语义查询的数据服务,为用户和上层应用程序提供基于语义的数据访问和共享服务；用户和上层应用程序通过全局语义数据模型,以即需即用的方式,直接访问分布、异构、关联关系复杂的底层数据源。应用结果表明,OPODSS可提供全面、高效的数据服务。

For mass,distributed,heterogeneous data sources of oil production engineering,an oil production engineering ontolo-gy-based data service system (OPODSS)was proposed based on building global semantic mode.Semantic-based data services were provided.With the semantic-based data query and sharing service,users directly accessed distributed and heterogeneous da-ta sources through the global semantic data model.OPODSS was used by upper applications.The results show that OPODSS is efficient in providing comprehensive and real-time data services,saving energy,and improving production.
