摘要

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 research,we present a seismic trace interpolation method which uses seismic data with surface-related multiples.It is different from conventional seismic data interpolation using information transformation or extrapolation of adjacent channels for reconstruction of missing seismic data.In this method there are two steps,first,we construct pseudo-primaries by cross-correlation of surface multiple data to extract the missing nearoffset information in multiples,which are not displayed in the acquired seismic record.Second,we correct the pseudo-primaries by applying a Least-squares Matching Filter (LMF) and RMS amplitude correction method in time and space sliding windows.Then the corrected pseudo-primaries can be used to fill the data gaps.The method is easy to implement,without the need to separate multiples and primaries.It extracts the seismic information contained by multiples for filling missing traces.The method is suitable for seismic data with surfacerelated multiples.
