摘　　要：为降低动平台在埕岛油田反复插拔桩地区的就位风险,对反复插拔桩形成的不均匀海床通过海底地形地貌调查、规划治理范围和深度并选择合适机械进行定位施工、预后分析等海底修复措施,最后通过案例分析该海底修复方法在实际工程中的应用,该海底修复方法可以增加桩靴入泥深度,减少动平台滑桩、穿刺风险。In order to reduce the risk of the moving platform being in place in the area of repeated pile insertion and extraction in Chengdao Oilfield,the uneven seabed formed by repeated pile insertion and extraction is repaired through seabed topography and geomorphology investigation,planning of treatment scope and depth,selection of suitable machinery for construction,positioning construction,prognosis analysis,etc.Through case analysis,this seabed repair can increase the depth of pile shoes entering the mud,reduce the risk of sliding piles and puncture on the moving platform.
