Abstract：The method for computing the zero-offset VSP forward model in the case of horizontal beds is given. Its essential steps are (1) to use the velocities and thicknesses of beds to convert the stratigraphic system whose independent variable is depth into the stratigraphic system of which the independent variable is one-way travel time; (2) to perform discretization of the stratigraphic system by making use of fixed time interval; (3) to adopt wave equation to construct a transmission network of wave fields in whole stratigraphic system, by which various multiple reflections can be simulated. Examples show that zero-offset VSP forward model can be computed fast and correctly using this method.
