中文摘要：

多次波是地下反射层的多次波反射，也蕴含了地下反射界面的信息，因此并不是绝对地只能被当做噪音来处理．为实现对地下构造的准确成像，本文基于广义概念上的炮偏移成像算法，对常规一次波偏移方法从用于向下延拓的上、下行场以及成像条件方面进行了改进，将同时含有表层多次波的炮记录与脉冲震源之和作为下行延拓的震源波场，将同时含有表层多次波和一次波的炮记录作为接收波场，并应用2D反褶积成像条件进行成像，实现了表层多次波和一次波联合成像．在数值试验部分，通过对相对简单的五层模型和Sigsbee2b模型数据的数值测试表明，该方法可以很大程度上压制常规成像方法中由多次波带来的成像噪音．

英文摘要：

In this paper, a generalized traditional shot-profile migration is presented to jointly image primaries and surface-related multiples. This method replaces the impulsive source with sum of impulsive source and recorded primaries and surface related multiples, and the extrapolated wavefield at the receivers consists of recorded primaries and surface-related multiples. To achieve crosstalk suppression, the method introduces a 2D deconvolution imaging condition. A simple five-layers model and complex Sigsbee2b synthetic data are used to test the method. Results show that the method is effective to suppress the crosstalk artifacts generated by interference of upgoing and downgoing events not associated with the same subsurface reflection points.
