摘要
本文概述了地震道奇性特征的意义,提出了一种子波分离、反褶积循环迭代奇性分析算法。采用理论模型进行了试算,同时与其它算法进行了比较,效果理想。对实际的地震资料单炮记录和偏移剖面记录实施该法,分辨率有较大的提高,效果显著。由此可见,奇性算法是实现高分辨率处理的一种有效途径。
The meaning of singularity of seismic trace is sketched here. A circulative iteration algorithm of deconvolution and singularity analysis is used to achieve wavelet separation. This algorithm has been tried theoretically and compared with others,showing desirable result. The algorithm has been also applied to single-fold seismic data and migrated seismic section,bringing much improved resolution. It can be seen from this that the algorithm is an effective one for improving resolution.
