Numerical Simulation on the Relationship between Spatial Sampling Density and Resolution

摘要

The relationship between spatial sampling density and resolution is an important research topic in the high-density seismic acquisition techniques.We in this paper study the relationship between trace interval and resolution qualitatively and quantitatively by forward modeling.Under the different spatial sampling densities,we simulate collapse column and Ordovician unconformity,and results show that trace interval affects vertical resolution of migrated section by changing the max alias-free frequency.Besides,small trace interval haves obvious advantage for precise imaging of the small structure,and improving lateral resolution.
