摘　　要：考虑面波特征和古龙断陷区地震资料面波强的特点,提出面波压制的十字交叉排列法.该方法将地震资料中的炮点线和检波点线重排后,进行三维Fourier变换;在频率—波数域滤波后,进行Fourier反变换,实现面波压制处理.古龙断陷区地震资料面波压制结果表明,十字交叉排列面波压制方法具有很好的保幅性和实用性,能够为地震资料保幅处理提供较好的叠前预处理方法,可以在深层地震资料处理中推广应用.Surface wave is the main coherent noise in seismic data processing,its characterization is low velocity,low frequency in temporal frequency domain,strong energy and slowness in attenuation.It is very important to suppress surface wave in seismic data preprocessing for enhancing S/N ration and improving temporal resolution.The cross-spread surface suppressing approach is proposed based on 3D Fourier transform of seismic data,comparison of different surface wave suppression result between cross-spread and traditional zone filter approach,the result demonstrates that the proposed approach in this article not only remove surface wave completely,but also preserve the primary efficiently,this means that the proposed technique is validity and applicable in seismic data prestack preprocessing,and also has better application prospects.
