摘　　要：本文根据振动基本原理,结合深水浮式钻井平台在海面受波浪运动的影响特点和运动规律,建立了浮式钻井平台的受迫振动方程和动力响应。在此基础上,进一步研究了钻井作业过程中,浮式钻井平台的隔水导管在不同悬挂方式条件下的振动规律和特点,并且探索了深水浮式钻井平台所悬挂的隔水导管不同的长度,以及不同防喷器和水下连接器的重量、浮式钻井平台固有频率的影响和变化规律。结合现场的钻井平台操作的环境条件,对深水平台的避台风过程中出现的问题进行了回顾和分析。这对我们在复杂海况条件下,合理地认识浮式钻井平台的作业条件,选择恰当的解脱方式,保障钻井作业和操作的安全具有十分重要的指导意义。according to the basic principle of mechanical vibration,the forced vibration equation and dynamic response of the floating drilling platform are established in this paper.On this basis,the vibration law and characteristics of the riser of the floating drilling platform under different suspension modes are further studied in the process of drilling operation,and the different lengths of the riser suspended on the Deepwater Floating drilling platform,the weight of different BOP and underwater connector,and the influence and change law of the natural frequency of the floating drilling platform are explored.Combined with the environmental conditions of drilling platform operation,the problems in the process of typhoon avoidance of deepwater platform are reviewed and analyzed.This is very important for us to understand the operating conditions of floating drilling platform,choose the appropriate way of relief,and ensure the safety of drilling operation and operation under complex sea conditions.
