In 3-D seismic exploration, first, field layout is designed in accordance with the requirement that there are at least three sampling points in the width of a smallest fault block which must be ascertained; then, data acquisition is made; finally, in data processing, the field seismic data are interpolated according to required line spacing and CDP spacing.
