摘要： 利用子波处理与子波整形技术,结合匹配滤波,可以很好地将不同震源及不同条件下施工的地震测线拼接在一起,且拼接处没有明显的差异。基本解决了拼接目标处理中存在的几个突出问题:拼接段相位的闭合差;处理剖面子波的统一;确保振幅的相对关系和极性的一致性。利用该技术可为地震资料的解释提供真实可靠的地震拼接剖面。

Abstract: Seismic survey lines which are operated from different seismic sources and under different conditions can be jointed together quite well using the wavelet Processing and wavelet shaping technologies in combination with matched filtering. This method has basically solved some conspicuous problems present in processing of spliced objects, including closure error of factes in spliced section, unification of the processed profile wavelets and conformity of relative correlation and polarity of the amplitude. The technique can provide true and reliable seismic spliced profiles for seismic data interpretation.

Key words: seismic data, survey line splicing, wavelet Processing, matched filtering
