Abstract：The paper considered by analyzing 3-D practical high-density data in A area of east China that it is no necessary to put undue stress on small size when choosing bin size for improving resolution,and it's folds making more contribution to high-frequency components,which got following knowledge:①the choice of bin size should mainly start from meeting the needs of no the highest folding frequency,of lateral resolution and diffraction convergence within 30 degree of migration aperture;②in an aspect of fold selection,it should emphasize the need of S/N ratio in high-frequency end of prospecting bandwidth in major targets according to the requirement of geologic task and determine the fold required based on S/N ratio required for prospecting major targets and estimated S/N ratio of raw data.
