摘要
Abstract
It's difficult to conduct the OBC seismic operation in the area with obstacles on the sea.The positions of shot or receiver have to be changed by obstacles, and it may even result in gaps on profile.Meanwhile, this can low the number of folds and reduce the quality of seismic data.The ranges, types and distributions of normal obstacles and their influences of OBC seismic operation are discussed in this paper.By analyzing characteristics of source-ship and obstacles, a method of calculating the minimum safe distance is formed.Furthermore, the special design is used to adjust the actual operation in order to reduce the loss of seismic data.Both of the methods are used to ensure the safety of operation and the quality of seismic data.关键词
