%X To reveal the wave-field characters of cave reservoir,the paper adopt a phase-shift plus in interpolation wave-field extrapolation operator which can preserve amplitude and suppress inter-bed harmonic wave without restrictions horizontal land vertical changes of medium velocity and layer dip angle.The operator is then used in the forward modeling and migration on the five beads-shaped cave models that based on the geologic features of the corroded caves in an Ordovician reservoir and the resulting wave-field is analyzed.Numerical simulation of the beads-shaped caves show the wave-field features of beads-shaped caves reservoir in different size,different shape,different distance,different distribution position situations and obtain some significant the conclusions.
