摘　　要：针对渤海油田锦州25-1井隔水导管在钻入过程中遇阻,未下入到位,且未采取固井措施的情况,采用建立隔水导管受力模型及有限元模型的方法,应用ANSYS软件分析该井隔水导管在风、流、冰荷载作用下的承载力及井口稳定性,确定在最危险工况下和承受防喷器重量时隔水导管承载能力满足作业要求,在复杂环境荷载作用下井口稳定性满足要求。For the complex conditions that the riser of Bohai Oilfield JZ25-1 did not drill to specified depth and the cementing measures were not taken, the riser mechanics modeling and finite element model are set up to analyze the riser＇s bearing capacity and wellhead stability under the loadings of wind, current and ice loads, etc. the numerical results show that the riser car- rying capacity in the most dangerous conditions and withstanding the weight of the BOP can meet the operational requirements, and the wellhead stability in complex environments loads can also meet the operational requirements.
