摘要: 在二维地震资料处理工作中,控制静校正参数的闭合差可以改善地震剖面的闭合差。 通过建立全塔里木盆地北部探区的地表低速带数据库对二三维低速带数据进行整理。搜索和剔除奇异值。然后输入数据库.建立稳定的可重复使用的近地表低速带模型.再采用统一的计算模式进行平滑、内插.导出生成网格化的低速带数据.为资料处理快速提供可靠的低速带数据既可以缩短处理周期.也可改善剖面的闭合差。

Abstract: In 2-D seismic data processing, to control the discrepancy in closing of static correction parameters tends to improvethe discrepancy in closing of seismic profile.Through establishing a database of surface low-velocity layer of Tabei area in Tarimbasin, coordinating data from 2-D and 3-D low-velocity layer, searching and eliminating singular values, and then inputting them .into the database, this paper develops a model of surface low-velocity layer that can be used steadily and repeatedly, by whichobtains the gridding low-velocity layer data generated after smoothing and interpolation using uniform calculation method.Usingsuch a model database can not only shorten the data processing cycle, but also improve the discrepancy in closing of seismicprofile fleetly and reliably.

Key words: seismic exploration, seismic data processing, static correction, low-velocity layer, model, database
