海底地震采集技术发展现状及建议

与海上拖缆地震采集相比,海底地震采集技术在某些方面具有独特优势,其应用市场日益繁荣,未来发展前景也普遍看好。近些年,海底地震采集技术取得飞速发展,不管是海底电缆采集,还是海底节点采集,新方法、新装备层出不穷,而国内在这一领域仍处于初步应用阶段。除海底地震仪之外,相关核心装备研发更是处于近空白状态,某些掌握前沿核心技术的西方公司多出于商业竞争目的,一般仅提供技术服务,因此国内开展相关装备技术的自主研发势在必行。此文详细介绍了海底地震采集技术的优缺点、装备现状及趋势,以期对国内相关研究提供一定参考。

Current Development Situations and Suggestion on the Techniques of Ocean Bottom Seismic Acquisition

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.
