为了克服以往叠前地震资料拼接处理中存在的不足,从叠后记录入手求取整形算子,在叠前道集中实现整形匹配滤波,使得不同特征的资料能够在频率、相位、振幅上相一致,从而完成叠前资料的拼接。实际资料应用表明,该方法求取的整形算子稳定,简单易行,应用效果理想,能为后续的处理提供高质量的叠前道集数据,是实现连片处理的一种较好的方法。

In order to overcome the disadvantages in the conventional prestack seismic data splicing processing , the post stack record was used to obtain shaping operators. Then the shaping matched filtering is perormed. This technique makes the seismic data with different characteristics consistent on frequency , phase and mplitude ,and carries out the prestack seismic data splicing. The practical application of the technique showed that it could provide high quality prestack gathers for subsequent processing , by which the shaping operators obtained are stable and easy to perform , and that it is assuredly a good choice for block-tie processing.
