【摘要】 目前，人们开发了地震资料叠后高分辨处理的多种方法，使地震资料的分辨率得到不同程度的提高，但信噪比却下降了，从而使物探解释人员不敢大量地使用这种叠后高分辨资料作层位对比和油气解释。为了改变这样的局面，本文利用二维小波变换作了地震资料的叠后高分辨处理。理论和实践都证明，这种方法不仅使地震资料的分辨率得到较大提高，而且信噪比不降低，是较为理想的一种叠后高分辨处理方法。更多还原

【Abstract】 The currently developed poststack high resolution processing techniques can increase seismicresolution to different levels but decrease signal-noise ratio. Thus interpreters dare not rely onthese techniques too much in their work of stratigraphic correlation. To get out of this cmbarrasingsituation we propose to utilize two dimensional wavelet trandform in poststack high resolutionprocessing of seismic data. It can be demonstrated that the proposed method can increase theresolution of seismic data a lot without decrcasing its signal-noise ratio and is one of the relativelyideal methods in poststack high resolution processing techniques.更多还原
