摘要
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 poststack record was used to obtain shaping operators.Then the shaping matched filtering is performed.This technique makes the seismic data with different characteristics consistent on frequency,phase and amplitude,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.
