摘要
介绍了一种结构简单、用钢量少、海上安装简便的简易井口架结构,利用环境条件较为恶劣的南海某海域的井位资料,对该井口架结构的承载能力进行了ANSYS分析。结果表明,设计的井口架结构许用应力284 MPa,最大水平位移337 mm,满足应力要求,在边际油气田的初期开采过程中可有效降低投资成本,具有良好的推广应用前景。
A kind of well-head support,which consists of underwater centralizer and riser system,will be introduced in this paper.The simple structure has the advantages of saving steel,easy to be installed and so on.The structure design as per the working condition and stress analysis based on ANSYS will be detailed in this paper.From the results,it finds that the structure is feasible and can be widely used in the initial development of marginal oil-gas field;thus greatly reduce the investment cost.
