摘　　要：重点分析观测系统引起"采集脚印"的原因,研究观测系统引起的"采集脚印"对地震资料属性以及储层预测的影响,通过自适应滤波方法消除"采集脚印",在叠后地震数据体上压制"采集脚印"干扰。通过分析对比滤除"采集脚印"前后地震资料属性以及储层预测效果,研究"采集脚印"的影响及其消除方法。This paper deals with the problem of ＂acquisition footprint＂ in recording geometry. The effect of ＂acquisition footprint＂ on the seismic attributes and reservoir prediction was first analyzed, and then the self-adaptive filtering method was used to eliminate the ＂ acquisition footprint＂, thus inhibiting the interference of ＂acquisition footprint＂ in the post-stack seismic data. Based on an analysis of the effects on seismic attributes and reservoir prediction before and after eliminating the ＂acquisition footprint＂, the authors put forward a method for eliminating acquisition footprint.
