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.
