【摘要】 基于小波变换的相干体算法,开发出相干体分析软件,对实际地震数据进行处理,结合地质资料进行了综合分析。研究结果表明,对于品质不同的地震资料,选择适当的小波变换参数及相干处理参数,可以得到特定频带的相干体;选择不同权值对分频计算得到的相干体重构,可以得到突出特定频带的相干体。与传统相干处理结果相比,更能突出不同层次的地质特征。更多还原

【Abstract】 The coherent cube technique is applied to detect the discontinuity of seismic wave events.The paper introduces the algorithm of the coherence cube on the basis of wavelet transform.The authors develop the software of the coherence cube technique,educe the applied examples of the coherence cube technique and do effect analysis in the paper.The study result shows that one can choose the proper wavelet transform parameter and appropriate coherent processing parameter to the seismic data of different qualities,so as to extract the coherence cube in a given frequency division;one can also reconstruct the coherence cube that calculate in frequency division through different weights,so as to stand out the coherence cube of a given frequency.So one can obtain the geological structure characteristics of different levels.更多还原
