摘　　要：该文依托新型液缸举升系统,研究隔水管柱下放水下防喷器和钻柱下放水下采油树的数学模型,以探究钻柱补偿功能辅助水下设备精准操作的可行性和性能。在AMESim软件平台上搭建液缸举升系统水下安装工况仿真模型,进行4级海况下开启和关闭主动钻柱补偿时水下安装工况的仿真研究,分析单次提升下放操作的最大安全操作高度,探讨不同海况对于水下安装作业的影响。研究表明:液缸举升系统因其自身具备的主动补偿功能,大幅提高了水下安装作业的安全性,作业海况对水下安装的作业窗口和极限操作高度均有较大影响。该研究结果可为液缸举升系统的国产工程化落地及现场应用提供一定的理论指导。The mathematical models of the marine riser lowering blowout preventer(BOP)and the drill string lowering subsea Xmas tree are studied based on new type of cylinder hoisting system,in order to explore the feasibility of accurate operation and the performance of the auxiliary underwater equipment with drilling string compensation function.A simulation model of a cylinder hoisting system under the subsea installation condition is built on the AMESim platform.The subsea installation is simulated when the active drill string compensation is opened and closed under the class 4 sea condition.The maximum safe operation height of a single lifting and lowering operation is analyzed to discuss the impact of different sea conditions on the subsea installation.The results show that the cylinder hoisting system greatly improve the safety of the subsea installation due to its own active compensation function,and the sea condition has a great influence on the operation window and limit operation height.The research results can provide certain theoretical guidance for the national engineering implementation and the field application of the cylinder hoisting system.
