摘要
提出一种导管架式钻井平台井口扩建方案。该方案可以有效解决老平台由于预留井槽不足,导致无法在原平台井口处加设生产井的问题。新增结构与平台原有结构之间通过水上导向桩进行连接,这样做可以避免水下焊接施工,同时也降低了对安装精度的要求。对改造后平台进行抗震、抗冰性能分析,结果表明改造后平台各方面性能均满足要求。
To increase the production in marginal field,more wells are going to be drilled,but there was not enough deck area on old jacket platforms.The application of legs extension-additional technology for old jacket platform solved this problem effectively.New legs are added for support-ing the new structure which meets the demand of enlarging the wellhead area.A horn shape con-nections are designed to avoid underwater welding and reduce the accuracy requirements during the process of installation.The results of punching shear check for major member and joint,pile capacity check in seismic analysis and ice resistance analysis show that the platform meet the spec-ification requirements.
