摘要
在深入分析OBC双源数据特点以及有关分离技术特点的基础上,综合应用矢量中值滤波和异常振幅衰减等干扰压制类技术,对A区的实际OBC双源数据进行分离,取得了满意的分离效果,并探索出了一套适用于海量海上多源同步激发数据分离的应用流程。
Based on detailed analysis of OBC data acquired by multi-source shooting and the properties of various de-blending techniques,we carry out noise attenuation with vector median filter and abnormal amplitude attenuation on OBC data sets acquired with a dual-source shooting,and obtain satisfying de-blending result.At the same time,we present a practical OBC data de-blending work flow for massive marine data acquired with multi-source simultaneous shooting.
