基于ANSYS Workbench的钻井平台就位方式 改进建议

Suggestions for improving positioning mode of drilling platform based on ANSYS Workbench

在近海石油钻井作业中自升式钻井平台占据主要地位,而自升式钻井平台中的桁架式桩腿平台以其独有的优势渐渐成为主力军。拖航就位方式的不同,对桁架式桩腿的影响差别巨大。以某桁架式钻井平台作为研究实例,首先运用UG三维建模软件对某桁架式钻井平台桩腿进行三维建模,其次运用ANSYS有限元分析软件对桩腿的受力变形情况进行分析,最终根据桩腿的变形情况提出平台就位方式的改进建议。

Jack-up drilling platforms play the major role in offshore oil drilling operations,among them,the truss type pile leg platforms have gradually become the main role due to their unique advantages.Different towing and positioning modes have great influence on the truss type pile legs.Taking a truss type drilling platform as an research example,this paper uses UG three-dimensional modeling software to carry out three-dimensional modeling of the pile legs of the truss drilling platform,then uses ANSYS finite element analysis software to analyze the stress and deformation of the pile legs.Finally,it puts forward the improvement suggestion on the platform positioning mode according to the deformation of the pile legs.
