Abstract This paper discusses a F-K field deviation imaging technique-recursion F-K deviation, which is developed by combination of the normal speed F-K deviation with the deviation of phase-shift method characterized by verticalvarying velocity. Under the condition of horizontal layered media, the devia-tion precision of this method is not restricted by the dip angle, and its calcu-lation time is considerably shorter than that of the phase shift method. Byintroducing the concept of series deviation, We have putforward a new develop-ment of recursion F-K deviation-residual recursion F-K deviation. Theo-retical and practical data processing shows that this deviation method canfurther raise deviation precision and calculation efficiency.
