Abstract 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.
