理想的地震剖面只存在一次反射波,即震波在界而上只反射一次。然而,实际上的记录剖面或多或少会被多次波所扰乱,即被反射的波往往多于一次。最糟糕的是这些多次波可以在界面上与一次波同时到达并具有足够的振幅与一次波相混淆。简单的共反射点迭加通常是足以压制多次波的,但在有些地区对多次波作些补充压制也是必要的。在迭加前对资料作适当的加权可以使结果进一步改善。本文叙述了一种确定最佳加权的方法,并展示了处理的实际结果。最初的权决定于被迭加的一次波和多次波模型。然后逐步变更各道的权值,直至找 There is only one reflected wave in the ideal seismic profile, ie the seismic wave only reflects once in the boundary. However, the actual recording profile is more or less disrupted by multiple waves, ie the reflected wave tends to be more than once. The worst part is that these multiple waves can arrive at the same time with the primary wave at the interface and have enough amplitude to be confused with the primary wave. Simple co-reflection point stacking is usually sufficient to suppress multiple waves, but in some areas to replenish multiple waves is also necessary. The appropriate weighting of the data prior to stacking can further improve the results. This article describes a way to determine the best weight, and shows the actual results of the process. The initial weight depends on the primary and multiple models that are superimposed. Then gradually change the weight of each track until you find it
