摘　　要：油井工程领域涉及的数据具有分布、异构和自治性强等特点,并且存在复杂的语义关联,无法为全局决策提供有效的数据支持。利用本体和虚拟视图集成技术,提出了油井工程虚拟数据中心解决方案,通过构造领域全局本体并利用本体抽取、本体映射和查询转换实现领域数据语义集成,提供了统一和基于语义的数据查询与共享服务。实际应用表明,虚拟数据中心能够为油井生产决策提供全面和实时的数据支持。The data involved in the field of oil-well-engineering are distributed,heterogeneous and autonomous,and there is also a complex semantic association among them.Under this circumstance,effective global support for decision-making is difficult to ensure.Using integration technology of ontology and virtual view,this paper presented a virtual data center solution for oil-well data integration.Through global-ontology construction,ontology extraction,ontology mapping and query conversion,the data in oil-well engineering field can be semantically integrated.Consequently,a unified and semantic-based data query and shared services were achieved.By practical application,this virtual data center is able to supply production decision with comprehensive and real-time data services.
