【摘要】 在塔里木沙漠地区,静校正技术是地震资料处理的一项关键技术。文中对该区静校正问题进行了分析,从低、降速带的分层,浮动基准面的建立,静校正中高频分量的处理方法以及剩余静校正等方面做了一些探讨,提出了用分偏移距地表一致性剩余静校正方法解决该区剩余静校正问题。实际资料处理效果良好。更多还原

【Abstract】 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.更多还原
