摘　　要：随着近海油气勘探程度的不断深入,中浅层构造型油气藏占比大幅减少,深水、中深层、超浅层、潜山、岩性和复杂构造领域已成为油气增储上产新的增长极,对地震勘探技术提出新的挑战.为破解这些复杂领域的地质难题,基于变观测系统的小面元、高覆盖、超长偏移距、宽/多方位节点等地震采集方式不断涌现,作业方式变得越发复杂,在提升复杂地质条件下地震资料品质的同时,也带来了采集成本的大幅攀升.践行价值勘探开发理念,通过海洋地震勘探技术创新降低采集成本,引领油气高质量发展迫在眉睫.介绍了主要几种国内外海洋经济高效地震采集技术,重点分析了海洋地震勘探技术发展现状、应用成效及前景.在改善海洋地震资料品质、提高采集作业效率的同时,降低采集成本,发展经济技术一体化海洋地震勘探技术,推动产业高质量发展,实2现价值勘探开发.With the deepening of offshore oil and gas exploration in China,the proportion of tectonic oil and gas reservoirs has decreased significantly,and complex fields such as deep layer,buried hill,and lithology have become new growth poles in the searching of offshore oil and gas.This poses a new challenge to seismic exploration technology.In order to solve the geological problems in these complex fields,seismic acquisition methods such as small bins,high folds,ultra-long offsets,wide/multi azimuth Ocean Bottom Nodes are constantly emerging.The geometry and operation methods for offshore seismic acquisition have become increasingly complex,leading to a substantial increase in the cost of acquisition while enhancing the quality of seismic data under complex offshore geological conditions.It is urgent to practice the concept of value-driven exploration,reduce acquisition cost through technical innovation,and lead the high-quality development of offshore seismic exploration.This paper focuses on introducing several efficient offshore seismic acquisition technologies,including analysis of current status,applications,and prospects of technological development.While improving the quality of offshore seismic data and enhancing exploration efficiency,concerted efforts are made to raise acquisition efficiency and develop an economically and technically integrated offshore seismic exploration technology.This is essential for achieving value-driven exploration and promoting the high-quality development of offshore oil and gas exploration.
