摘　　要：针对自安装井口平台需要在目标油田进行长期作业不撤离的特点,提出一种适用于自安装井口平台的无浮力式桩靴,桩靴设有新型的自适应式封堵楔块结构,通过封堵楔块运动解决平台站立状态时的桩腿浮力对平台的不利影响,使用有限元法对桩靴结构本体、封堵楔块在平台插桩和站立作业状态时的受力情况进行数值模拟分析,结果表明,新型自安装井口平台桩靴安全。Aiming at the characteristic that self-installing wellhead platform needs long-term operation in oilfield without evacuation,a non-buoyancy spudcan was designed.The spudcan has a new type of adaptive sealing wedge structure,which can solve the adverse effect of the buoyancy of the spud-leg when the platform is standing.The finite element method was used to analyze the stress of the spudcan structure and the sealing wedge when the platform is in the state of pile insertion and standing operation.The safety of the new designed self-installing wellhead platform spudcan was verified.
