相干体数据体与常规地震数据体相比, 更能清楚地识别断层和地层特征, 而多尺度相干体分析方法更是揭示复杂地质细节和地层内部特征的良好方法。从多尺度分析的地质含义出发, 给出了多尺度分析的方法原理, 分析总结了相干体算法的特点。将该方法应用于潜山油藏内部特征分析, 取得了较常规地震更为明显的效果。

Coherence cube can clearly reveal faults and stratal characters as compared with conventional seismic cube. Multi-scale coherence cube analysis is an ideal method to unveil geologic details and stratal characters. This paper discusses geologic meanings of multi-scale analysis, presents principles of multi-resolution analysis, and summarizes characteristics of coherency cube algorithm. Satisfactory results have been achieved by applying the method to the analysis of buried hill hydrocarbon reservoir.
