Abstract：Seismic response in viscoelastic medium is discussed here,The assumption is made that P-wave velocity,S-wave velocity,density and Q factor show lateral piecewise linear continuous variations in block media,Under the above assumption,mathematical model for making seismic time section with the use of viscoelastic wave equation is developed; the relewant finite-element wave equation is derived; and the calculation method for the finite-element equation,including stiffness matrix and damping matrix,is given in the paper,The effect of simulating a real horizontal stack section shows that this method is feasible.
