叠前地震资料的去噪处理

Noise-removing processing for prestack seismic data.

目前,有多种去噪方法适用于叠后资料的处理,相对来说,叠前资料的去噪工作研究得不够。文中结合李庆忠先生提出的一维迭代去噪方法,重点讨论叠前资料的去噪问题。通过处理实例分析,叠前去噪要比叠后去噪的效果有明显的改进。因此,在重视叠后资料去噪处理的同时,应加强对叠前资料去噪方法的研究与应用。

There are several noise-removing methods for poststack seismic data.Noise-re- moving research on prestack seismic data is relatively not enough.Noise-removing processing for prestack seismic data is emphatically discussed with refercnce to Mr. Li Qingzhong's one-dimensional iterative noise-removing method.It is practically shown that prestack noise removing brings much better result than poststack noise removing.Therefore,we should not only pay more attention to noise removing pro- cessing for poststack seismic data but also study and use noise-removing method for prestack seismic data.
