摘　　要：针对自升式钻井平台在特定地层插桩时穿刺事故对钻井平台带来的危害,介绍漂浮压载方法,基于某钻井平台在导管架处的压载法实例来说明漂浮压载法实施的条件和步骤,实例表明,漂浮压载相比于常规压载能有效防止钻井平台突然穿刺对自升式钻井平台桩腿和船体带来的伤害,可保证钻井平台的就位安全,提高现场压载效率。For the damage of penetration accident on drilling rig when jack-up drilling rig penetrates in specific formation, a new preloading method, floating preload method, is presented based on a drilling rig preloads in the jacket to describe the condi-tion and procedure of floating preload.In-situ preloading shows that comparing with the conventional preload method, the floating preload method is able to effectively prevent sudden penetration of jack-up drilling rig leg and hull damage, to ensure the safe lo-cation of the drilling rig, to improve the efficiency of the field preloading.
