简介：Common-reflection-point(CRP)集合是连接地震数据和petrophysical参数的一座桥。预先叠属性抽取并且预先叠倒置，他们俩是水库预言的重要工具。CRP集合的质量通常在地震探索的精确性上有大影响。因此，预先叠CRP集合噪音抑制技术成为一个主要研究方向。基于向量分解原则，这里，我们建议一个方法压制噪音。这个方法由在各种各样的方向寻找估计最佳的单位向量然后通过向量角度变光滑和限制压制噪音。模型测试显示建议方法能把有效信号与噪音分开很好并且在单个wavenumber大小写中有效地压制随机的噪音。我们到真实数据的方法的申请证明方法能恢复有效信号，好振幅保存了从预先叠甚至在到噪音比率(SNR)的低信号的情况中的吵闹的地震数据。
