摘要
在前人研究基础上提出一种半主动浮式钻井平台钻柱升沉补偿方案,将被动补偿能耗低和主动补偿精度高的特点有机结合在一起。建立系统数学模型,在仿真基础上,设计并搭建升沉补偿试验台,进行被动、主动和半主动的升沉补偿试验。结果表明,基于蓄能器的半主动升沉补偿系统收敛速度快,性能稳定,补偿效果较好,可以补偿平台97%的升沉运动。
For floating drilling platform, a new type of semi-active drill string heave compensation system was designed, as- sembling the advantages of passive and active compensator into one whole. A mathematical model was built, and with the result of simulation, the heave compensation test bed was built. A great number of experiments for passive, active and semi-ac- tive heave compensation indicate that the semi-active heave compensation system is of fast convergence, stable performance and more effective in compensation effect. The system can compensate for 97% of the heave motion.
