| 摘 要： | 由于受地震资料本身的分辨率和保真度的限制,如何识别地震上难于人工解释的小断层一直是期待解决的问题。在珠江口盆地X油田,通过测试蚂蚁体技术、相干体技术、曲率技术等这几种当前最主要的小断层识别方法,以断层识别要求为标准对比分析了其识别能力,最终总结出以蚂蚁体为主,相干分析为辅,并结合地震剖面及本区构造特征进行综合识别的小断层检测方案。实际应用效果表明,该方法在相应尺度小断层的识别效果较好,满足了开发工程的需求。

| Abstract: | Due to the limitation of resolution and fidelity in seismic data, it is always a problem how to identify small fault of the seismic, at X oilfield on the pearl river mouth basin, through the tests of ant body technology, coherence technology, curvature technology which are the main small fault identification method currently, take the fault identification requirement as the stand ard, comparing and analyzing recognition ability, and finally summed up a comprehensive recognition of small fault detection scheme which give ant body as priority, supplemented by coherence analysis, and combining seismic profile and area structure features, the applied results indicate that the method recognition effect is better in the corresponding scale small faults, thereby meet the needs of the development projects. |
