Abstract：Authors recommend a fast algorithm by which logging curve as model can be used to make synthetic vertical seismic profile (SVSP).The algorithm,based on wave equation,calculates wave field by recurrence in frequency domain.The calculated wave field includes primary reflection and all multiples.A method is discussed which can effectively remove‘time-domain' abasing caused by discrete Fourier transform,Examples show that the fast algorithm needs less internal storage and is practical in production.It takes 5 minutes at most to calculate a practical SVSP using the PIMP 11⁄45 minicomputer.
