摘要:

为了降低海洋钻井电动绞车补偿系统的能耗、实现升沉补偿运动与自动送钻运动的解耦控制,开展了补偿绞车的节能方法及控制策略研究。针对系统大惯性、大负载的特点,提出一种基于混合动力与液压能量回收的新型液压绞车补偿系统,通过被动液压马达承担钻柱的部分静载荷,通过液压二次调节元件克服运动过程中的其余载荷,同时利用液压蓄能器实现对系统位能与动能的周期性回收与再利用。提出一种基于升沉-送钻双位移闭环控制的软件解耦控制策略;设计了液压绞车补偿系统的串级控制结构;建立了补偿系统的仿真模型并研制了一套补偿绞车原理样机。仿真与实验结果表明,液压绞车补偿系统的解耦控制效果良好,相对于电动绞车补偿系统的节能效果明显。

Abstract:

To reduce the energy consumption of electrodynamic winch compensation system for offshore drilling and realize the decoupling control of heave compensation movement and automatic bit feed movement, the research was carried out on the energy-saving method and control strategy of compensation winch. Due to large inertia and heavy load characteristics of the system, a new type of hydraulic winch compensation system was proposed on the basis of hybrid and hydraulic energy recovery. The passive hydraulic motor was able to bear part of drill-string static load, and hydraulic secondary regulating elements were used to overcome the rest load during the movement. Meanwhile, hydraulic accumulators were adopted to achieve the periodic recovery and reutilization of system potential energy and kinetic energy. Software decoupling control strategy was put forward based on the dual closed loop control of heave and bit feed displacement, and the cascade control structure of hydraulic winch compensation system was designed. Finally, a simulation model of compensation system was established, and a principle prototype of compensation winch was developed. Simulation and experimental results show that the decoupling control effect of hydraulic winch compensation system is favorable with more significant energy saving effect than the electrodynamic winch compensation system.
