摘　　要：多次波压制日益成为单道地震资料处理的焦点,其关键技术之一是自适应匹配滤波。然而,传统匹配滤波算法不总适合描述随时间和空间非平稳变化的地震信号,针对这一问题正则化非平稳回归技术被提出。从基本原理出发,采用模型数据对正则化参数进行了试验,并获得了它们对处理效果的影响特性,最后将该技术用于实际资料的多次波预测减去过程中,取得了良好的多次波压制效果。通过实际应用对比,证实该技术较传统匹配滤波方法在去除多次波方面更具优势。Multiples attenuation is critical for single channel seismic data processing,and the adaptive matched filtering is one of the key techniques to be used for the purpose.However,the traditional matched filtering algorithms are not always adequate to the description of nonstationary seismic signal changes with time and space.To solve this problem,the regularized nonstationary regression is proposed.This paper studies the application of regularized nonstationary regression,starting from basic principles,then testing regularization parameters using model data to pursue their influence on processing effect,and finally applying this technology to predict subtraction process of field data.As the result,multiples are effectively attenuated.Practical application demonstrates that the method has great advantages comparing to the traditional method in multiple attenuation.
