%X For heterogeneous data sources of oil engineering domain, this paper presented a semantic-based virtual view integration method. By ontology extraction and merging process, built local ontology of data sources and global ontology to achieve semantic-based data access view. Using mapping information among these ontologies and data sources, could convert semantic search statement to queries on underlying data sources. This method provided a unified and transparent data access view and could avoid the problem of frequent data loading and updating. Through applying in well decision support data-integration-platform, this method achieves a good application effect.
