纯相位因子估算与剩余子波相位校正
Keywords: 纯相位因子,相位校正,特征方程,剩余子波,分辨率
Abstract:
？常相位校正处理方法将剩余子波相位作为一个常数，这种假设仅仅是一种近似。当子波的振幅谱很窄时，此法会有一定效果。如果子波振幅谱较宽，对不同频率采用同一个常数相位进行校正，很难达到期望的效果。本文应用纯相位校正处理方法可以实现剩余子波非常数相位校正处理。此法包括纯相位因子估算与校正处理方法，即通过构造纯相位因子特征方程，直接计算纯相位因子，以实现地震数据中剩余子波的纯相位校正处理，消除地震数据剩余子波相位影响，提高地震数据的分辨率。理论数据和实际地震资料处理结果验证了此法的有效性和实用性。
