| 摘 要： | 为消除剩余动校正量对CMP道集的影响，研究了带有剩余动校正量的CMP道集内反射波接收时间与偏移距之间的关系，得到了剩余时差函数。这个函数是带有平移量的双曲线函数。利用最大能量准则，我们能够在CMP道集上确定剩余动校正量，进而消除剩余动校正量。理论计算和实际应用表明，该方法的处理效果良好。

| Abstract: | To remove the influence of residual normal moveout on seismic data, we investigate relations between time and offset of the seismic data with residual normal movement in the CMP gather. In this paper, we presented a function about time and offset of seismic data with residual normal moveout. This function is a hyperbola with shift. By using the maximum power criterion, we can estimate and remove the residual normal moveout. Theoretical and real results show that the method is promising. |

| Keywords: | residual normal moveout dynamic correction hyperbola maximum power criterion |
