摘　　要：海底地震勘探实施过程中,传统的缆绳式地震节点布设方式受洋流及海底地形影响较大,很难保证节点的数据采集质量和设备安全性。由于无人缆控潜水器(Remote Operated Vehicle,ROV)对海洋环境的良好适应性和强大的工程干预能力,为探索海底地震节点布设提供了新方法。笔者综合介绍了ROV的技术特点,结合具体工程实例讨论了基于ROV的海底地震节点布设的主要技术流程。通过分析对比采用ROV布放与传统甲板布放在布放回收效率、安全性及复杂地形适应性等方面的工作数据统计,探讨了ROV布放技术在海底地震节点放工作中的可行性、优势与局限性,以及其应用发展前沿。具有更高精度和安全性的ROV节点布放技术作为一种新手段,可作为传统布放方式的补充手段,未来将在深远海的海底地震节点布设及其相关领域得到更广泛的应用。The traditional submarine cable seismic node layout is greatly affected by water current and seabed topography, which make it difficult to ensure the quality of data acquisition and equipment safety. However, the ROV has excellent adaptability and engineering intervention ability to marine environment. In order to explore a new method for submarine seismic node layout, this paper discussed the feasibility of underwater seismic node deployment by ROV system. We compared it with the traditional water surface deployment, and both the advantages and limitations of ROV technology, and future prospects of the technology are presented and analyzed. As a new method, ROV node layout technology with higher accuracy and safety can be used as a supplement to the traditional layout method. In the future, it will be widely used in the submarine seismic node layout and related fields.
