独立桩脚自升式钻井平台在我国海洋石油勘探开发中的应用已有三十多年的历史，在长期平台插桩分析工作的基础，虽然积累了丰富的经验，但面对新的勘探区域，也会出现预测不准的情况。究其原因主要是对场地土质条件了解不够充分、土质参数评价不够准确、计算模型过于单一和地区经验积累不足等。为提高插桩分析结果的准确性，通过多次工程插桩实践，总结了插桩分析几个需重点关注问题。结合某工程实例，在考虑这些关键问题的基础上，得到插桩分析预测结果与实际插桩结果基本吻合。
獨立樁腳自升式鑽井平檯在我國海洋石油勘探開髮中的應用已有三十多年的歷史，在長期平檯插樁分析工作的基礎，雖然積纍瞭豐富的經驗，但麵對新的勘探區域，也會齣現預測不準的情況。究其原因主要是對場地土質條件瞭解不夠充分、土質參數評價不夠準確、計算模型過于單一和地區經驗積纍不足等。為提高插樁分析結果的準確性，通過多次工程插樁實踐，總結瞭插樁分析幾箇需重點關註問題。結閤某工程實例，在攷慮這些關鍵問題的基礎上，得到插樁分析預測結果與實際插樁結果基本吻閤。

The Jack-up rig has been utilized in the development of offshore oil for more than thirty years in China. A lot of Jack-up rig leg penetration analysis has been carried out and rich experiences have been accumulated. However, the predicted leg penetration results were inconsistent with those actual leg penetration results in some new oilfield development area. The main reasons lay in the insufficient understanding of soil properties, unsuitable soil parameters, simplicity of calculation model and the lackness of local experiences etc. To improve the accuracy of predicted penetration, the important considerations for jack-up rig leg penetration analysis were summarized through many engineering practices in this paper. The predicted results coincided with the actual results based on those considerations in an actual case.
