摘　　要：实际地震资料往往存在很强的随机噪声,干扰有效信号,有时甚至看不清同相轴,使地震资料品质大大降低。通过改进的FastICA方法对理论模型进行处理分析,得到良好的去噪效果,并且对实际地震资料进行处理,不仅能够有效地去除资料中随机噪声,而且能够保护有效信号,取得了良好的效果,表明改进的FastICA方法是有效的。The field seismic data often have strong random noise, interfere with the effective signal, sometimes even cannot see the events, make the quality of seismic data is reduced greatly. In this article, through processing and analysis of the theo-retical model, getting good effect of denoising, and applying to the actual seismic data processing, these can not only effectively remove the random noise in the data, and also protect the effective signal, good results have been achieved. This indicates that the method is effective.
