| 摘 要： | 利用VSP资料所包含的高频信息,可以提高三维地面地震资料的分辨率。本文提出一种新的子波置换法——将地面地震记录中的子波,置换为零偏VSP的子波,在资料处理中通过子波置换反褶积实现。理论子波与倾斜地层模型实验证明了子波置换反褶积方法的效能。实际地震资料的处理效果表明,该方法可以有效地提高地震反射波的主频和高截频,同时较好地保护信号的低频成分,从而拓宽地面地震信号的频带宽度,提高地面地震资料的分辨率。

| Abstract: | The high frequency information in VSP data can be used to enhance the resolution of 3D surface seismic data.A new method-wavelet replacement is presented in this study. The wavelet of surface seismic data is permuted by wavelet from VSP of zero offset.It is realized by wavelet replacement deconvolution in data processing.The efficiency of this method is proved by theoretical wavelet computation and slanting layers modeling.The correlation of wavelet can be derived from seismic records in real data processin... |
