摘　　要：相干体技术用于检测地震波同相轴的不连续性,可以用来识别断层、特殊岩性体、河道等,为三维地震资料解释提供了技术手段。本文介绍了相干体技术3种算法线性互相关算法、多道相似算法和本征结构分析算法,在微机上开发出相干体分析软件,给出了相干体技术应用实例和效果分析。研究结果表明,对于品质不同的地震资料,可以选择精度合适的算法、适当的相干处理参数,以得到更加精确的相干体。The coherent cube technique is applied to detecting the discontinuity of seismic wave events, which can identify faults, special lithology and channels, so that has provided technology and method. This paper has introduced three algorithms of coherence cube technique ： linear cross- correlation algorithm, multi- trace semblance algorithm and eigenstructure analysis algorithm. We have developed the software of coherence cube technique, educed the applied examples of coherence cube technique and effect analysis. The study result shows that we can choose the algorithm with proper precision and appropriate coherent processing parameter to the seismic data of different quality, so as to extract more precise coherence cube.
