摘　　要：通过对桃子荡地区资料处理试验,找到了一种适应桃子荡地区地震资料成像处理的策略方案:先采用层析静校正消除近地表的影响,再针对性叠前去噪压制各种强能量干扰,同时进行保真保幅处理,然后实施自地表开始的叠前时间偏移完成最终成像。从实际资料处理效果可以看到本次策略方案较好的消除了复杂地区近地表对地震资料成像的影响,提高了成像品质。Abstract：Through the data processing test in the taozidang area, we have found a peach to taozidang area seismic data imaging processing strategy： firstly, using tomographic statics correction to eliminate near-surface influences, and then targeted pre-stacknoiseattenuation press all kinds of strong-energy noise, and fidelity amplitude processing, and since the implementation of pre-stack time migration of surface to complete the final image. It can be seen from the actual data processing results that this method can eliminated the influence of the near surface on the seismic data in complex areas, and improved the imaging quality.
