| Abstract: | 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 au... |
