Abstract：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.
