Abstract:For complex data sources of oil and gas engineering, this paper summarizes characteristics and semanticrelationships of oil data, and presents a semantic-based data service for oil and gas engineering (SDSOge).The domain semantic data model is constructed using ontology technology, and semantic-based dataintegration is achieved by ontology extraction, ontology mapping, query translation, and data cleaning. Withthe semantic-based data query and sharing service, users can directly access distributed and heterogeneousdata sources through the global semantic data model. SDSOge has been used by upper applications, and theresults show that SDSOge is efficient in providing a comprehensive and real-time data service, savingenergy, and improving production.
