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.
