Abstract: The research on massive-scale geographic data was carried on for a long time. But general formation data has not been studied carefully. According to the data features of exploration and development on oil&gas field, the paper proposed a way for organizing and managing massive-scale formation data, making da to prepared for large scale geographic spatial modeling and real
time visualization. The fast accessing, indexing and spatial tomputation algorithm is based on data redistribution, oct-tree indexing and technology such as predication.
