摘要
摘要:基于反馈模型的地表相关多次波消除方法SRME（Surface-Related Multiple Elimination）近年来已得到了广泛的应用.利用共聚焦点CFP（Common Focus Point）道集代替炮集，可以将该方法扩展至层间多次波的消除.地表数据驱动的层间多次波消除方法直接利用地表观测数据进行层间多次波预测，避免了构建CFP道集所需的聚焦运算，特别是与层相关的层间多次波消除方法有效提高了多次波预测的计算效率.但地表数据驱动的与层相关的层间多次波消除方法并没有从理论上被严格地推导证明，其与CFP方法之间的关系亦未被讨论.本文在CFP方法的理论基础上推导了地表数据驱动的与层相关的层间多次波消除方法，阐明了CFP方法与地表数据驱动方法之间的内在联系.并将该方法应用于模型数据和野外实际数据，应用实例表明了所提方法的有效性.

Abstract:In recent years, the Surface-Related Multiple Elimination (SRME) method based on the feedback model has been widely used. This approach can be extended to removing inter-bed multiples by replacing shot records with Common-Focus-Point (CFP) gathers. The surface-based Inter-layer Multiple Elimination (IME) method directly uses surface data to predict multiples, avoiding focusing calculation in construction of CFP gathers, hence the computation time is reduced significantly, especially in the layer-related algorithm. However the surface-based layer-related IME method has not been deduced strictly, and the relationship between the surface-based method and CFP-based method has not been discussed yet. In this paper, based on the CFP-based IME method, we deduce the surface-based layer-related IME algorithm, which avoids the defects mentioned above and remains high effective at the same time. We explain the intrinsic relationship between surface-based and CFP-based IME methods during the derivation. Synthetic and field data examples show the effectiveness of the proposed method.
