| 摘 要： | 埕岛油田具有新近系披覆、古近系超覆和前第三系潜山3层构造，断裂系统比较复杂。笔者利用相干分析和倾角扫描方法，进行垦东30～垦东48地区地震资料属性的特征分析及断裂系统的识别。通过研究相干分析、地震属性与断裂系统的关系以及倾角扫描、层间属性提取与断裂系统的关系，对研究区进行应用效果分析，同时应用RAVE特征可视化，对所选的地震属性和识别方法进行验证，说明哪些属性能够很好的反应断裂系统，哪些识别方法在研究区识别断裂系统的效果明显。

| Abstract: | As a typical duplex concentration area of oil and gas, the Chengdao oil field has three layer structure composed of Neogene drape, Paleogene overlap and Pre Tertiary. In order to analyze attributes of seismic data and work out a method for recognizing the fault system, this paper deals with some relative attributes and two methods for identifying the fault system, i.e., coherence analysis and dip scanning. With the Kendong 30 Kendong 48 area as an example and according to the researches on the relationships between coherence analysis, seismic attribute and fault system as well as the relationships between dip scanning, interlayer attribute extraction and fault system, the authors made application analysis and indicated which attributes can better reflect the fault system. The RAVE attribute visualization was also employed to verify the chosen seismic attributes and recognition method, and the results obtained prove that the recognition methods can identify the fault system quite obviously. |
