The bin size determines the full and continuity of the seismic wavefield sampling. Combined with the fold, symmetry, full and continuity of seismic wavefield sampling can be used to determine the imaging capability of a 3D geometry, though it is not so direct. Based on the 3D exploration effect of the buried hill reservoir in B Basin, Africa, the paper discusses the selection of imaging trace density, trace area and OVT imaging processing. It is required to process the data of anisotropic geological body on azimuth. The paper proposes the concept of single azimuth imaging trace density and single azimuth folds, which can be used to calculate the total folds. The higher the total imaging trace density and single azimuth imaging trace density, the smaller the trace area, the higher the imaging capability of the 3D geometry. The physical meanings of imaging trace density and trace area are clear, which can be directly used to estimate the imaging capability of the 3D geometry.
