Static Correction in Desert Area in Tarim Basin

Static correction is a key technique in seismic pro-cessing in desert areas in Tarim basin.Application of static correction is analyzed in respects of layering in low-velocity zone and subweathered zone,establishment of floating datum,processing methods of high frequency components and residual static correction.A component offset distance surface-consistent static correction method is presented to solve the problem of residual static cor-rection.Real data processing results with this technique are of high quality.
