摘要

以琼东南深海三维地震资料为例,全面分析深海地震资料特点,深入分析深海干扰波的类型和特点。针对不同类型的干扰波,采用不同的处理方法,开展针对深海地震资料叠前去噪处理技术研究。通过研究深海地震多次波压制、水鸟干扰压制、涌浪干扰和异常振幅压制等处理方法,总结出针对深海地震资料的叠前去噪技术,为今后的深海地震资料处理工作奠定了技术基础。
Taking 3D seismic data from the deep sea in Qiongdongnan basin as an example,characteristics of the seismic data,and types and characteristics of interference waves in deep water were analyzed comprehensively.Aiming at different types of interference waves,we attenuated the interference waves using different approaches such as carried out the research of the seismic data pre-stack noise attenuation technology in deep water.By studying these approach of multiple suppression,eliminating the interference by aquatic bird and surge,and eliminating the abnormal amplitude in deep water,we summed up the seismic data pre-stack noise attenuation technology in deep water.It is the technical foundation for future seismic data processing in deep water.
