Abstract: Based on SINOPEC's pilot project -Study on Exploration Well Deployment Decision Support System-, according to the comprehensive requirement of exploration well deployment work of the petroleum industry for exploration information, a set of exploration well deployment decision support solutions are proposed. By fully using exploration database and information technology, a comprehensive exploration information application platform that integrates g data management, data inquiry, and visual display is built to provide researchers with useful data, enable the management department to master the project flow without delay, offer decision makers accurate and reliable basis to make decisions with great convenience, low risk and high efficiency. On the basis of the application of database technology to exploration well deployment decision in oilfield, it gets feasible to transform traditional work flow and patterns in exploration domains of petroleum industry and promote the overall level of exploration with high efficiency. It has a definite value as reference to domestic oil exploration industry
