| 英文摘要 | In explicit depth extrapolation method of frequency-space fields, wavefield depth extrapolation is completed with convolution of short explicit difference operators and the wavefield. Based on the study of the method of creating short explicit difference operators, a method for creating short explicit operators is presented, which is based on discrete smooth interpolation with control of phase-shift operator. In the wavefield-spread area, we uses the phase-shift operator as constraint in frequency-wavenumber field, while beyond the wavefield-spread data, we uses zero point at the ends of phase-shift operator as constraint to take discrete smooth interpolation so that the resulted operator satisfies two-order smooth and the length of this operator can be selected shorter in frequency-space field. This method has simple creating process and high precision, and can be used in wave fields depth extrapolation. |
