| 摘 要： | AVO技术主要用于研究地震波振幅随偏移距变化的规律,三维地震资料的偏移距分布情况直接影响AVO处理的效果.老资料在设计施工时并没有兼顾AVO技术的特殊需要,造成AVO属性在一定程度上失真.笔者针对这些问题,分析了AVO对三维地震观测系统设计的要求,提出了一种AVO观测系统,既适合常规三维地震勘探,又能满足AVO技术的特殊需要. |
| 关 键 词： | 地震勘探 三维观测系统 AVO 偏移距 |

| Abstract: | The AVO technique is mainly used to study the variation regularity of seismic wave amplitude with the migration distance, and the distribution of the 3D seismic data directly influences the effects of AVO processing. The designing and utilizing of old 3D data failed to consider the special requirements of AVO technique, which caused some degrees of distortion in AVO attribute. Aimed at solving this problem, this paper has analyzed the requirements of AVO for the designing of the 3D observational system and put forward an AVO observational system, which can not only suit the traditional 3D exploration but also meet the specific needs of the AVO technique. |
| Keywords: | seismic exploration 3D observational system AVO migration distance |
