The multiple sources of the field spatial data, the heterogeneity between the spatial data and the exploration and development (E&D) data, the diversity of the application systems and other issues seriously hampered the construction and application of geographic information in Oil field. Aiming at the above problems and adapting to the actual demand, a spatial data storage model is designed and the spatial database of oil E&D is established so that a unified management and maintenance for spatial data of E&D is achieved. Furthermore, the integrated E&D geographic information services and data services are created that make the graphical objects display in multi-plane scale and form a combination of graphics and data models and technologies. Finally, a universal geographic information service integration application mode is built, so a new application for geographic information is expanded in oil soft. The research results have solved the GIS data sources, the storage methods, the application mode and other issues of oil E&D. The system has been running on the line that has important practical significance for oil field information.
