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。
The coherence body data more clearly identifies faults and stratigraphic features than conventional seismic data bodies, and the multi-scale coherence analysis method is a good way to reveal complex geological details and stratigraphic features. Based on the geological meaning of multi-scale analysis, the principle of multi-scale analysis is given, and the characteristics of coherence algorithm are analyzed and summarized. The method is applied to the internal characteristic analysis of buried hill reservoirs, and has achieved more obvious effects than conventional earthquakes.
