本文提出基于原始含表层多次波数据实现叠前共炮集地震数据插值。相对于利用相邻道的信息变换或外推插值用于缺失的地震数据重建,本文方法利用表层多次波数据互相关构建准一次波,将蕴含在表层多次波数据中的,而在采集记录中表现为缺失的近炮检距信息提取出来,并在滑动时间空间窗内采用最小二乘匹配滤波和均方根振幅校正方法进行准一次波校正而后用于数据插值重建。本文方法适用于表层多次波比较发育,同时又存在数据缺失尤其是近炮检距数据缺失情况。方法易于实现,不需多次波和一次波的提取,利用多次波中蕴含的信息实现缺失的地震数据弥补,为含有表层多次波的数据进行近炮检距地震信息的插值重建提供了一个很好的思路。
In this paper, we propose a pre-stack common shot set seismic data interpolation based on the original surface-covered multiple-wave data. Compared with the information transformation or extrapolation interpolation using adjacent tracks for the missing seismic data reconstruction, the method of this paper constructs the quasi-first-order wave using the cross-correlation of the surface multiple wave data, and implies the data contained in the surface multiple wave data. The near-offset information, which appears to be missing in the record, was extracted and corrected by quasi-first-order wavelets in the sliding time-space window using the least-squares matched filter and root mean square amplitude correction method for data interpolation reconstruction. This method is suitable for the comparative development of surface multiple waves, and at the same time, there is a lack of data, especially near offset data. The method is easy to implement without the need of multiple and primary wave extraction. The missing information of seismic data can be compensated by using the information contained in the multiple waves, and the interpolation and reconstruction of the seismic data near the offset can be provided for the data with surface multiple waves A good idea.
