摘　　要：CL-FCZ三维地表条件复杂,工区内有大运河、GY城区、高铁及燃气管道。地震采集中应用了多种激发方式联合施工,地震资料的一致性存在差异;运河区的复杂近地表条件产生了静校正问题,使地震成像更加困难。在资料处理过程中,通过可控震源资料最小相位化、层析静校正和匹配滤波等处理方法,较有效地解决了井炮和可控震源采集数据的一致性差异及近地表速度变化所引起的静校正问题,改善了剖面的成像效果。The three-dimensional surface conditions of CL-FCZ are complex,and there are the Grand Canal,GY urban area,high-speed railroad,and gas pipeline in the work zone.Multiple excitation methods are applied in seismic acquisition for joint construction,and the consistency of seismic data is different.The complex near-surface conditions in the canal zone produce the static correction problem,making seismic imaging more challenging.In data processing,the static correction problem caused by the consistency difference and the near-surface velocity variation between well gun and vibroseis data were solved more effectively through minimum phasing,tomographic static correction,and matching filter,improving the profiles'imaging effect.
