By dint of the time-depth transformation, the F-K migration was made suitable for the state of variable velocity. Because of the data needed to process was always finite in length and discre-tized, it may produce the boundary effects at the end point and bring about the alias as well. Hence, the terms following related to the coordinate sys- terns should be taken into account carefully and seriously: the sampling intervals,...             本文以变换的观点出发来讨论F—K偏移,通过虚速度时深变换的方法,使F—K偏移适应于速度有变化的情况.由于要处理的数据总是有限长的和离散化的,前者会引起端部的边界效应,后者可能产生假频现象,这就要求我们考虑在各个坐标系中所选用的采样间隔的大小、数据道延伸的长短、边界二端的补零道、网格和接头等一系列问题.本文讨论了与这些问题有关的参数意义和选择原则,适当地选取这些参数能提高处理的效率和改善剖面的质量.本文提供了用变速F—K偏移方法计算的模型和实例.计算结果说明变速F—K偏移具有处理效率高、适应于陡倾角偏移和用来做反偏移等特点.变速的F—K偏移对速度变化较敏感,在速度变化较迅速的情况下,建议进行速度光滑. 文摘来源   << 更多相关文摘         相关查询: 深时 时深校正 深时转换 时深曲线 时深转换 时—深转换 深—时转换 时 变速时深转换 时深转换速度 深时转换模型 时-深转换  对查询结果不满意
