摘要
多次波一直是影响地震处理与解释的主要因素之一.本文基于表层相关多次波衰减(Surface RelatedMultiple Elimination,SRME)理论,对其进行一定的改造,使其可以预测出海底电缆(Ocean Bottom Cable,OBC)数据中所有与表层相关的多次波,而后将预测出的多次波自适应减去.本文对OBC波场,OBC多次波的压制方法给出了介绍,对SRME方法压制OBC多次波理论给出了洋尽的阐述.利用SRME理论预测OBC多次波完全数据驱动,不需要地下介质的任何信息,理论数据验证了方法的有效性.
Multiple is always a key factor influencing seismic processing and interpretation. We make some improvement over the well known SRME theory, and predict all surface-related multiple in OBC datasets-this is followed by an adaptive subtraction to remove them. We give an overview to OBC wave-field and its multiple attenuation methods. And OBC multiple attenuation technique using SRME theory is illustrated. This technique is totally data driven, and no subsurface information is needed. Synthetic data examples illustrate the validity of this method.
