摘　　要：文章介绍了采集脚印的基本概念和由来,以模型资料研究结果为例,指出了采集脚印的基本特征,阐述了解决采集脚印的四种方法:①采用宽方位角采集;②提高覆盖次数;③基于照明度分析、面向地质目标的观测系统设计;④选择合适的观测系统参数。对于采集脚印处理,则重点介绍了二维波数域滤波方法,并给出了处理流程、应用实例和效果比较。This paper firstly introduces the origin and conception of seismic acquisition footprint and then shows its characteristics on the basis of model data.Secondly,it recommends four ways to eliminate seismic acquisition footprints:1)adopting wide-azimuth acquisition system,2)improving fold,3)the design of geometry based on the illumination analysis and facing geological targets,4)choosing appropriate parameters of survey.To eliminate this noise,the paper importantly introduces the technology of 2-D wave-number filtering,and gives its procedures,actual examples and comparison of results.
