摘要：Permanent guide base (PGB) is an important basic structure that guarantees the successful docking between subsea Christmas tree and subsea wellhead. Due to complex wave flow disturbance in the docking process, a great challenge and safety risk are encountered during the installation of a subsea Christmas tree. In view of this, the paper establishes the force analysis model of ship-wire rope-subsea Christmas tree-PGB coupled system, and analyzes the dynamic responds of wire rope and subsea Christmas tree using infinitesimal method and six-free-degree equation, respectively. Meanwhile, a numerical model for the process of connecting subsea Christmas tree and PGB has been established according to the actual sea conditions of an oil-gas field in the South China Sea. For the most dangerous stage Ⅰ and stage Ⅱ, this paper analyzes the stressing influence of different sea currents on the installation posture of subsea Christmas tree and PGB, reveals the causes and mechanism for topping and detachment of the guide pile, explores the dynamic response regularity of subsea Christmas tree and PGB in the docking process under the incentive of ship heaving and sea current at different stages of docking, and checks PGB intensity according to the working conditions of different periods. The results shows that the topping and detachment of No. 1 and 4 guide pile is easily to occur in stage Ⅰ and stage Ⅱ, respectively; in these two stages, the guide piles of PGB can both meet strength requirements, thus guaranteeing the safe working conditions. These research results have been effectively applied in the guiding installation of PGB in an oilfield of the South China Sea. ? 2022, Editorial Office of ACTA PETROLEI SINICA. All right reserved.
