Abstract
Abstract Petroleum reservoir modeling integrates multi- discipline research works which involve much more data type, huge data and complex data-flow. It is very important to bring the spatial data-mining (SDM) method into reservoir modeling. According to the characterization of reservoir modeling procedure, spatial data-mining can be used in reservoir geological research and ranking reservoir modeling. Geo-statistical method, spatial analysis method, visualizing method and non-linear method are the most effective methods for reservoir modeling based on the type of reservoir knowledge. Spatial-overlapping method is used for studying the relationship between sedimentary micro-facies and oil production with statistical method. The distribution knowledge of sedimentary micro-facies is built by geo-statistical method. The visualization method is used for checking the exactness of reservoir model. The application in Wenxi I Block of Tuha oil field is shown that spatial data-mining technology not only improves the efficient of reservoir modeling, but also verifies the knowledge obtained from each researching stage so as to guarantee the integrality and exactness of reservoir knowledge.
