地震资料中的多次波能量主要与地表的大反射率有关。提出了一种通过从数据中去除表面反射率的影响来消除所有与表面有关的倍数的方法。所提出的多重消除过程的一个重要特性是不需要地下表面的知识。另一方面，确实需要提供源签名和表面反射率。因此，建议的过程是自适应实施的，这意味着多次波消除被设计为一种反演过程，其中源和地表反射率属性被估计，并且无多次波的数据等于反演残差。模拟数据和现场数据的结果表明，多次波消除过程应被视为逐步地震反演的关键步骤之一。
The major amount of multiple energy in seismic data is related to the large reflectivity of the surface. A method is proposed for the elimination of all surface‐related multiples by means of a process that removes the influence of the surface reflectivity from the data. An important property of the proposed multiple elimination process is that no knowledge of the subsurface is required. On the other hand, the source signature and the surface reflectivity do need to be provided. As a consequence, the proposed process has been implemented adaptively, meaning that multiple elimination is designed as an inversion process where the source and surface reflectivity properties are estimated and where the multiple‐free data equals the inversion residue. Results on simulated data and field data show that the proposed multiple elimination process should be considered as one of the key inversion steps in stepwise seismic inversion.
