摘　　要：实现复杂波场高精度、高效率的成像处理是广大地球物理工作者追求的目标。但由于受到实际波场速度因素的影响,许多波场成像方法难以达到预期的效果。采用基于初始速度模型的相移插值偏移方法,经理论模型与实际资料处理结果表明,可提高高陡构造复杂波场的成像精度及效率。The most earth physics operator's object is to achieve high-precision and high-efficiency images of the complex wave field. However, because of the effective factor of practice wave field velocity, the most means of wave field imaging techniques are difficult to reach anticipation effect. This paper adopts the migration method of phase shift interpolation based on velocity model. The results of theory model and practice data processing indicate that the method improves precision and efficiency of images for the complex wave field with high steep structure.
