摘　　要：单道地震作为海上地震勘探测量方式的一种,采用自激自收的测量方式,具有施工效率高、资料处理解释快速的优点,广泛应用于海上地质调查。本文对单道地震资料处理方法进行了研究,提出了一整套处理流程,重点是采用SRME算法对多次波进行压制,提高数据信噪比。将上述算法应用于长岛海域单道地震资料处理,取得了良好的效果。As one of the marine seismic survey methods,the self-excitation and self-harvesting method has the advantages of high construction efficiency and fast data processing and interpretation.It is widely used in marine geological survey.In this paper,the processing method of single channel seismic data has been studied and a whole set of processing flow has been proposed.The focus is to use SRME algorithm to suppress multiple waves and improve the signal-to-noise ratio of data.The above algorithm has been applied to single channel seismic data in Changdao sea area,and good results have been obtained.
