The hydraulic compensator in marine drilling equipment plays a critical role in regulating the pressure balance between internal and external environments and the machine's oil supply rate. Its working principle involves utilizing seawater pressure to compensate for volumetric changes in hydraulic oil caused by deep-sea pressure and ambient temperature differences, thereby preventing seawater backflow and subsequent equipment corrosion. A mechanical volume analysis on two compensators with different shapes was conducted using Ansys software, and their hydraulic circuits were simulated via AMEsim. Based on the original hydraulic circuit, additional components such as pressure reducing valves, check valves, and overflow valves were incorporated to construct a hydraulic circuit suitable for active operation mode. A comparative analysis of flow velocity before and after the improvements was performed. Furthermore, the influence of different structural parameters on the internal flow field under deep-sea working conditions was investigated. Finally, a new hydraulic compensator was designed accounting for the pressure and temperature conditions of the marine environment. The results demonstrate that the compensator with a multilayer folded structure and an inlet/outlet size of 20 mm delivers optimal performance. Its hydraulic system can supply a larger flow rate within a shorter time and exhibits enhanced adaptive adjustment capability for transient flow variations.

深海钻探设备中的液压补偿器在调节内外压强平衡与机器供油速率方面具有重要作用，其工作原理是利用海水压力补偿因深海压力与环境温差所引起的液压油体积变化，从而防止海水倒灌导致设备腐蚀。基于Ansys软件对两种不同形状的补偿器容积进行了容积力学分析。并运用AMEsim对其液压回路进行了仿真模拟。在原有液压回路基础上，增设了减压阀、单向阀和溢流阀等元件，构建了一种适用于主动工作模式的液压回路，并对改进前后的流动速度进行了对比分析。同时研究了深海工况下不同结构参数对内部流场的影响。最后，基于该海洋环境压力与温度，设计了一种新型液压补偿器。研究结果表明：采用多层折叠结构、进出口尺寸为20 mm的补偿器性能最优，其液压系统可在更短时间内提供更大流量，并具备更强的瞬变流量自适应调整能力。
