摘要
Abstract
Due to the differences in acquisition parameters of seismic data in different oil fields,there are differences in am-plitude,frequency,phase time,etc.Matched filtering is one of the key technologies to eliminate these differences.This paper presents the pseudo-multi-channel matching filter technology,which can better adjust the amplitude,frequency,phase and ar-rival time differences between seismic data in different working areas and improve the matching effect of seismic data.The principle of the method is introduced systematically,and the method is tested and analyzed based on single-channel seismic da-ta.This method matches and stitches two seismic datasets acquired by different sources.Finally,the consistency of the data before and after stitching is analyzed using cross-correlation and time-frequency analysis,and the advantages of the method are verified.关键词
