摘　　要：复杂地区典型特征往往表现为近地表地质结构复杂,纵向、横向变化大,地下地质构造破碎,大倾角老地层出露。作者介绍了该类地区地震资料的主要特点;分析了处理好该类地震资料起决定性作用的静校正、去噪技术、频率补偿及偏移成像几个重要环节,并指出了生产中应注意的几个问题。Complex areas are characterized by complex near-surface geological structures, considerable variation in horizontal and vertical direction, fractured geological structures or the appearance of large dip angle old formation. This paper analyzes the main behaviors and the formation mechanisms of the seismic data in this area, and puts forward some processing techniques suitable for such areas, such as static correction, noise-elimination technique, and frequency compensation. Some problems deserving of attention are also pointed out.
