摘要
在海上地震勘探得到的记录上会见到很强的鸣震现象,海上纵波地震勘探难以将鸣震压制干净.海上多波地震勘探采集了4个分量的数据,可利用其中的P、Z分量压制海上鸣震.在研究了前人关于双检波器压制海上鸣震方法的基础上,提出了适合于实际生产的处理方法,取得了较好的效果.
There is strong reverberation in offshore seismic exploration. It is difficult to suppress the reverberation in P-wave exploration. Offshore multicomponent seismic exploration acquires four components data, the P and Z components offer a new method to suppress the reverberation. After studied predecessors' method of suppressing reverberation, a new processing method, which is fit to actual production, is proposed in this paper and got better result in actual data processing.
