The stacking method proposed here is to stack by erasing unreliable data with too strong noise, i e. to estimate the high signal to noise ratio in every recorded trace using quantitative method and erase the recorded traces with low signal to noise ratio so as to form a standard trace with high signal to noise ratio. Then all traces are compared with the standard one, and stacked after erasing the recorded traces with low relative coefficient. Actual seismic data procession shows the efficiency of this method to increase the signal to noise ratio of horizontal stacked profile, especially for inaverage signal to noise ratio in pre stack trace assemblage data.

在形成标准道时 ,利用定量估计信噪比的方法 ,对每个记录道分段进行信噪比估计 ,剔除信噪比低的记录段从而形成高信噪比的标准道。再将各道与标准道互相关 ,并把相关系数低的记录段剔除后进行叠加。实际地震资料处理表明 ,这种方法能够有效地提高水平叠加剖面的信噪比 ,尤其对于叠前的共中心点道集资料中信噪比不均衡的情况 ,效果更好。
