Performance And The Application Of The Seismic Data Storage Devices

With the progress of seismic exploration technology and the improvement of exploration,seismic exploration acquisition number increasing, the resulting seismic acquisition data ofmass increase. Collection of3d seismic exploration construction day today most is about15~30gb of data volume, large quantity of data in more than40gb;2d construction every day theamount of data collected is about3~10gb, more over10gb. Every day in the future, theearthquake team recorded seismic data volume also increased significantly. Therefore, the datastorage technology, data security, and data entry technology put forward higher request.As an important component of the seismic exploration instrument technology, seismicdata storage technology with seismic exploration technology, computer technology and thecontinuous development of material technology, information storage technology, fieldconstruction, acquisition of data recording equipment spot from the earliest simulationrecorder to tape machine, then to network disk, has experienced rapid development. With theprogress of seismic exploration technology and the improvement of exploration, seismicexploration acquisition number increasing, the resulting seismic acquisition data of massincrease. Record of equipment is commonly used in seismic prospecting at present: tapemachine mainly Fujitsu3490e tape machine, the IBM3592tape machine; Disk are mainly thevirtual tape machine, SERCEL NAS disk, etc. When seismic instrument data storageequipment type selection, should not only consider the data storage device for data recordingspeed, the requirement of data capacity, and backup requirements between the storage device,and to consider its adaptability to field construction environment.So in this paper, the storage devices, storage, backup, between data security and storagedevices are analyzed, and introduces a new kind of data storage software Copy+.
