QNAP数据存储与质控在高效采集项目中的应用

QNAP data storage and quality control in high efficient acquisition projects

目前,勘探队伍多采用IBM3592-E06磁带为媒介存储地震勘探采集SEG-D格式的地震数据,无论在常规勘探还是高效采集项目中,多数甲方均要求一盘磁带只能存储单线束的SEG-D格式的地震数据,这无疑会造成存储空间的浪费,而采用QNAP则可同时存储多线束数据,避免数据存储空间的浪费;另一方面,24小时不间断的高效采集可使日产量超过一万多炮,每日从野外仪器返回的数据量近2.5 TB,磁带数据的拷贝与质控耗时费力,而QNAP数据存储可在多个计算机节点上将多个线束的SEG-D格式的地震数据打包存储,从而大大减轻了物探队现场处理人员的工作强度。

At present, exploration teams mostly use IBM 3592-E06 tapes as the medium to store seismic data in SEG-D format for seismic exploration acquisition. Whether in regular exploration or efficient acquisition projects, most parties require that a tape can only store seismic data in SEG-D format for a single beam, which will undoubtedly cause a waste of storage space, while using QNAP can store data for multiple beams at the same time, avoiding a waste of data storage space. On the other hand, the 24-hour efficient acquisition can make the daily output more than 10,000 shots, and the daily data volume returned from field instruments is nearly 2.5 TB, which is time-consuming and laborious to copy and quality control the tape data. The QNAP data storage can package and store the seismic data in SEG-D format on multiple computer nodes, thus greatly reducing the workload of the physical exploration team.
