浅谈电缆羽角对2D资料的影响
|
摘要
电缆羽角在2D地震资料采集、处理中的影响往往容易被忽视,公开发表的对羽角研究的文章很少,本文在实例的基础上提出了适当的处理方法,以期更多有关羽角的研究方法问世。在没有资料比较时,对羽角的影响没有任何估计,但在野外做试验测线时,由于同一测线作多次,羽角也不尽相同,羽角问题明显,本文是一个实际例子。
It's used to be ignored of cable feather angle influence in the processing of 2D seismic data.There are little public articles related to the cable feather question.The suitable method is given in the paper based on the real data.We hope that more methods will come out.The influence isn't obvious when no compare.The phenomena of cable feather is obvious when several times work is done on the same line with different cable feather.This paper is a case.
