摘要: 以反馈迭代法(SRME)和逆数据域理论为基础, 利用互相关理论构建层间多次波, 将地震数据转换到逆数据域中, 对层间多次波进行压制。叠后及叠前地震数据的应用实例表明逆数据域层间多次波压制方法简单易行, 在有效衰减层间多次波的同时, 能够较好地保留一次波信息。

Abstract: The inverse data domain method is discussed to attenuate the internal multiples. This method is developed based on the SRME method, which constructs the internal multiples using the cross-correlation theory. By converting the data into the inverse data domain, the internal multiples can be eliminated easily. Some post-stack data and pre-stack data are introduced to testify the efficiency of the inverse data method, and the results confirm the potential for this method to attenuate the internal multiples.

Key words: seismic processing, multiple elimination, internal multiple, SRME, inverse data domain
