摘要
国内外对海量地形数据的研究比较深入,但对具有一般意义的海量地层数据研究较少。针对油气田勘探、开发领域的数据特点,建立海量地层数据组织和管理的一种途径,为大规模的三维地质建模、实时显示作数据准备。基于数据分区、八叉树索引、访问预测等相关技术,实现海量数据的快速访问、快速检索、空间算法等。
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 data prepared for large scale geographic spatial modeling and real time visualization. The fast accessing, indexing and spatial computation algorithm is based on data redistribution, oct-tree indexing and technology such as predication.
