摘要
“Footprint”, a kind of noise of 3D seismic, is mainly depend on seismic geometry. It harms amplitude fidelity during data acquisition, and affect badly processing and interpretation. In this paper, the authors propose a quantitative analysis method of 3D geometry footprint, which describe quantitatively the relationship between receiver parameter, source parameter and operation procedure. Considering the influence factors on footprint, this method can effectively suppress footprint from geometry design and optimize 3D seismic geometry.
