摘要
对波动方程叠前深度偏移中的平面波方法进行了深入的剖析 ,指出了平面波偏移方法能提高偏移计算效率的原因所在 ,这也是前人未曾涉及的。给出了平面波偏移方法在共炮点道集和共偏移距道集数据上的应用以及效果评价。
A detailed review on the plane wave migration method of wave equation pre stack depth migration is presented in this paper, to show why plane wave migration method can improve the computational efficiency of wave equation pre stack depth migration, which has not been reported before. Applications of plane wave migration method and their effectiveness on common shot gathers and common offset gathers are also presented.
