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。 At present, people have developed many methods of post-stack high-resolution seismic data processing to improve the resolution of seismic data to different extents, but the signal to noise ratio has declined, so that geophysical interpreters can not use such stacks extensively After high-resolution data for stratigraphic comparison and oil and gas interpretation. In order to change this situation, this paper makes use of two-dimensional wavelet transform to make post-stack high-resolution seismic data. Both theory and practice prove that this method not only greatly improves the resolution of seismic data, but also does not reduce the signal-to-noise ratio, which is an ideal post-stack high resolution processing method.
