| 中文摘要:在深海勘察取样作业时，由于海流作用会引起钻杆摆动或上下运动，这是导致取得样品失真的原因之一。海底基盘可在勘察作业过程中，对钻杆进行夹持稳定，以保障作业的质量，是提高勘察作业水平的核心装备之一。根据海洋石油708船的结构尺寸与勘察作业需求，研制了一套无缆海底基盘。目前该无缆基盘在我国南海及东海海域从事勘察作业服务，累计服务时间超过30个月，有力支撑了我国海洋地质调查工作。本文对该无缆基盘的工作参数及原理、水下液压系统以及通信与控制系统进行了介绍，重点对大容量深水电池的研制进行了分析。该电池能够保证无缆基盘的作业时间达到70 h，提高了勘察作业效率，可为今后相关海洋装备的研发提供基础。 |

| Abstract:In the process of deep water exploration and sampling， the swing or up and down movement of the drill pipe will be caused by the action of ocean current， which is one of the reasons leading to the distortion of obtained samples. The subsea frame is one of the key equipment to improve exploration and sampling offshore through clamping the drill pipe stably in exploration operations to ensure the samples quality. According to the size of the HYSY708 drilling ship and the requirement of exploration operation， a cable-free subsea frame was developed. So far， it has been employed in survey and sampling in the South China Sea and the East China Sea for more than 30 months， providing great support for the marine geological survey in China. In this paper， the working parameters and the principle of the subsea frame， the underwater hydraulic system， and the communication and control system are introduced with focus on analysis of the development of the deep water battery. The battery can ensure the operation time of the subsea frame up to 70h； thus， improving the survey operation efficiency. The product provides a foundation for the future research and development of relevant offshore drilling equipment. |
