| 摘 要： | 在海洋勘察和物探作业时,为了保证钻井系统钻具的稳定性和水下定位的准确性,研究开发了水下勘察基盘的核心部件——海底钳。概述了海底钳的工作原理,并根据其使用工况要求,设计了具有压力补偿功能的海底钳及深海液压驱动系统。压力补偿装置实现了液压系统内部压力的动态平衡,解决了液压系统动力源在水下运行的密封及耐水压问题,有效保障了海底钳工作的可靠性。同时对海底钳夹持钻具的失稳现象进行了探讨和分析,给出了夹持失稳的计算方法。研究结果可为海底钳的设计和制造提供理论指导。

| Abstract: | As the key component part of the seafloor template, the subsea pliers was studied and developed so as to guarantee the stability of the drilling tools and the accuracy of underwater positioning in marine geophysical prospecting and exploration operation. The operating principle of the pliers was summarized. The subsea pliers with the function of pressure compensation and the deepwater hydraulic driving system were designed according to the requirement of the operating condition of the pliers. The pressure c... |
