Abstract: For the sake of providing global petroleum geology and resources information to domestic petroleum industry employees, oil companies and social public, and hopefully boosting the acquisition and utilization of overseas resources, the Global Petroleum Resources Information System professional website has been developed and constructed by integrating the network-based petroleum geological knowledge management application system and professional website construction technology. In this information system, a series of data are publicly released online, including the independent research results such as petroleum geological characteristics, hydrocarbon enrichment and distribution rules, and resources potential of the major petroliferous basins in overseas areas, major regions and the whole world, as well as dynamic information of global petroleum industry and practical public industrial information. In addition, several key technologies have innovatively been developed, including knowledge fragmentation management of global petroleum resources assessment and automatic generation of standardized report,automatic acquisition and release of dynamic network resources, data driven automatic summarization and updating of petroleum resources assessment results, and automatic generation of template reports and forms, which effectively provide data, information and knowledge support services for scientific research and decision making of overseas oil and gas business, showing good application prospects.
