摘　　要：自升式钻井平台在浅海区的海洋石油开发中得到了广泛的应用。然而由于浅海油田海域地质及海况复杂,为规避穿刺风险,自升式平台大桩靴化是未来主要发展趋势,桩靴与桩腿组成的整体,是支撑平台上部结构的主要架式结构,也是钻井平台重要组成构件。本文介绍了自升式钻井平台“海洋石油941”的三个桩靴由直径17.98m加大到23m的适应性改造方案及工艺。Jack-up drilling platform has been widely used in offshore oil development in shallow sea area.However,due to the increasingly complex geology and sea conditions of shallow oil fields,jack-up platform with big spud cans is the main development trend in the future to avoid puncture risk.The integral combination of spud can and pile leg is the main frame structure supporting the superstructure of the platform as well as an important component of the drilling platform.This paper introduces the adaptive modification scheme and technology of three spud cans of the jack-up drilling platform"HYSY941"increasing from 17.98m to 23m in diameter.
