摘要 

本文首先讨论了常速F-K偏移与垂向变速的相移法偏移的结合而发展的一种F-K域偏移成像技术--递归F-K偏移.该方法在水平展状介质的前提下,偏移精度不受倾角限制且计算时间比相移法大大减少.串联偏移概念的引入,我们给出了递归F-K偏移的一个发展--剩余速归F-K偏移.理论与实际数据处理表明,该偏移方法可进一步提高偏移精度和计算效率.

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.
