【摘要】 在海洋地震勘探数据处理中,多次波被作为重要干扰波予以压制。对于不同类型多次波发育的情况,需要选择多个方法,优化组合,扬长避短,在保持有效反射的前提下,最大限度压制多次波。本文讨论了多次波压制方法的基本原理和应用条件,在此基础上,提出了组合压制的思路、模式和需要注意的问题。借助Promax地震数据处理系统,对Pluto2D模型模拟数据进行了组合压制方法应用。结果表明,以SRME法+Radon变换+内切除为主的多次波组合压制方案,在复杂海洋地质条件下,具有独特的优点和适用性,有一定的推广应用价值。更多还原

【Abstract】 Multiples are suppressed as important interference wave in the marine seismic data processing.When seismic data are rich in various kinds of multiples,a combined method by optimizing several data-matching methods can suppress all multiples sufficiently while the primaries are kept well.This paper discusses the principle and application conditions of multiple attenuation methods.On this basis,the paper carries out a study on combined suppressed thought,mode and some suggestions that should be noted in practice.Combination suppression method has been applied to Pluto 2Ddata mode with the seismic data processing system called Promax.The practice shows that the combined multi-suppression scheme based on SRME,hyperbolic Radon transform and internal resection is feasible and effective.The combined scheme has its unique advantage and applicability.更多还原
