Abstract: On the basis of analyzing the application of artificial intelligence and GIS in petroleum exploration and development and its existing problems, combining with the analysis of the basic characteristics and application potentialities of the two techniques, it discusses the advantage of integrating them from the perspectives of economy and technique. Then the author develops an idea that realizes the seamless integration of the two techniques and applies it in real conditions. What's more, the thesis discusses some relevant problems about the integration of basic data, software integration, and application integration, so as to build up an intelligent decision support system that combines data input, data management, and intelligent analysis

Key words: artificial intelligence, GIS, oil exploration and development, integrative application
