Abstract: Compared with towed streamer seismic acquisition,the technique of ocean bottom seismic acquisition has some significant advantages in some respects.Now there is a booming application market for ocean bottom seismic acquisition,and the development prospects are great.In recent years,great progress has been made in the technology of ocean bottom seismic acquisition.Both the ocean bottom cable (OBC) and ocean bottom node (OBN) are emerging in an endless stream.But the ocean bottom acquisition is still in the initial application stage in domestic,and the research of key equipment is almost in a blank state except ocean bottom seismograph.For the commercial competition,the western companies,which master the cutting-edge technology,only provide technical services instead of selling the technology and equipment.Therefore,independent research and development of the related equipment at home is imperative.This paper aims to provide some useful materials for the relative domestic research by introducing the main advantages and disadvantages,development situation and development tendency of the ocean bottom seismic acquisition technology.
