【摘要】 针对石油勘探行业海量数据过大以及非结构化的特点导致地震数据合并处理时的效率低、消耗磁盘等问题,提出对地震数据文件建立元数据,将多个独立地震数据文件通过文件元数据合并方式生成一个逻辑上完整的地震数据文件即虚拟地震数据文件,提高地震数据合并效率,并根据地震数据并行访问模型实现对虚拟地震数据文件的IO访问.更多还原

【Abstract】 In connection with the problems that the massive data file of petroleum exploration industry is too large and unstructured,poor efficiency and consuming disk while data combining,Virtual seismic data file what is a logically complete seismic data file consist of many complete seismic data files by the description of metadata was put forward,it improves the efficiency of seismic data mergence.And according to the seismic data parallel access model,we access the seismic data files.更多还原
