| 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 Related Multiple 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多次波理论给出了详尽的阐述.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.

| Abstract: | 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 sub-surface information is needed. Synthetic data examples illustrate the validity of this method. |
