摘要
近些年,海上OBC?OBN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,新装备、新方法层出不穷。笔者以最新的国内外研究成果和发表的论文为基础,总结了海上OBC?OBN技术的发展历史及研究现状,综述了有关海上四分量地震勘探采集技术及装备,以及处理与解释技术,认为:海底多分量地震相对于海上拖缆地震,具有多分量数据、宽方位、宽频等优势,是海上地震发展趋势;资料处理、转换波使用等方面尚需进一步研究;海上油气田勘探进入复杂构造、岩性油气藏勘探阶段,随着海底地震施工成本降低,处理技术的进步,其应用范围将得到进一步扩展。
In recent years,offshore OBC and OBN technology has achieved rapid development.Whether it is OBC acquisition or OBN acquisition,many new equipment and methods were developed.Based on the latest research results and published papers,this paper summarizes the development history and research status of offshore OBC and OBN technology,and summarizes the technology and e?quipment for offshore four?component seismic exploration and acquisition,as well as processing and interpretation techniques.It is con?sidered that the seabed multi?component seismic is the development trend of marine seismic,because it has the advantages of multi?com?ponent data,wide azimuth and wide frequency compared with the marine tow streamer.But the processing of data and conversion wave need to be researched.Now offshore oil and gas exploration is in the stage of complex structures and lithologic reservoirs,as the cost of submarine seismic decreases and the processing technology advances,it will be get more applications.
