摘要：
From Helmholtz wave equation, we derive in this paper the Fourier finite difference operator of prestack depth migration for walkaway VSP data and built a corresponding processing flow. Both numerical model tests and real data processing results show that the proposed prestack depth migration method for walkaway VSP data is suitable not only for strong lateral velocity variation, but also can accurately image complex steep-dip structures. © 2016, Editorial Department OIL GEOPHYSICAL PROSPECTING.
