摘　　要：在国外主动式绞车补偿方案的基础上,研发了一种具有自主知识产权的新型海洋浮式钻井平台半主动式绞车升沉补偿装置。通过设计新型绞车升沉补偿系统的结构与参数,分析了系统功率配置、节能效果与解耦控制的机理。研究结果表明:采用液压蓄能节能与电液联合驱动的方式可降低系统能耗;通过合理设计补偿绞车驱动装置结构及控制策略可实现钻柱升沉补偿运动与自动送钻运动的合成及解耦控制。通过建立补偿系统的数学模型并进行补偿性能仿真的结果显示,该系统具有良好补偿效果。In order to develop a drawworks heave compensation equipment of independent intellectual property right, a novel semi-ac- tive drawworks heave compensation system of marine floating drilling platform was developed based on using the foreign technology, ＇Active Heave Drilling Drawworks＇ as reference. The power configuration, energy saving effect and decoupling control mechanism of the system were analyzed through designing structures and parameters of this novel drawworks heave compensation system. The research results indicated that the system can reduce energy consumption by adopting a hydraulic accumulator to save energy and an electro-hydraulic compound drive mode, and realize the combination and deeoupling control of drilbstem heave compensation move- ment and automatic bit feeding movement by logically designing drive structures and control strategies of the drawworks heave corn pensation system. A mathematical model was built to simulate compensation capability and the results indicated that the system is of a good effect of compensation.
