| 摘 要： | 在叠前共深度点道集内各地震道的动、静校正误差很小的情况下，地震资料时间域水平叠加方法有较好的叠加结果。但是，如果动、静校正的误差较大时，叠加效果将受到影响，即叠后振幅和分辨率都会降低。因此，提出一种频率域叠加方法。该方法既具有常规水平叠加方法能提高信噪比的优点，又能将共深度点道集内的走时时差消除，达到内相叠回的目的。几个比较叠加方法效果的有噪CDP道集叠加的例子证明了该方法的效果。

| Abstract: | The conventional stack method of seismic data gives quite good results when the errors of time corrections are small enough or the arrivals are near the same. However the stack effect is severely influenced if the time corrections are not undertaken completely. The amplitude and resolution of the stacked trace decrease, sometimes seriously due to the errors of time corrections. This paper proposes a frequency domain stack method that remains the advantage of conventional method and can eliminate the time errors automatically during stacking. Some examples indicate the good effect of the novel method. |
