FIELD: geophysics, possible use for processing large volumes of seismic data in oil industry. ^ SUBSTANCE: in accordance to method and device for sorting large volumes of portions of seismic data in given order, portions of data are positioned in leaf files of B-tree structure and stored in appropriate area of temporary memory, appropriate for given leaf file. Filled leaf file is read into sorting memory area, where they are sorted in appropriate sub-order. All sorted data portions are dispensed in appropriate sub-orders for all filled leaf files in leaf order for creating final stream of output data, where data portions in their appropriate sub-orders for all filled leaf files in leaf order are positioned in given common order. ^ EFFECT: increased sorting efficiency for large volumes of seismic data. ^ 3 cl, 9 dwg |
