中文摘要:
      针对凝析油气田开发了一型适应我国南海环境条件的深水多功能干树半潜平台,平台运动性能优良,可实现干树开采、回接水下井口、油气生产处理、凝析油存储、钻修井等功能。平台由上部组块、主船体、细长柔性连接结构、垂荡板、顶张紧式立管(TTR立管)系统、系泊系统构成,结构特点为采用细长柔性连接结构连接主船体与箱型垂荡板。垂荡板采用箱型结构,承受作业吃水压力,可实现平台与箱型垂荡板的整体拖航,平台安装简易,细长柔性连接结构可在位维修或更换。平台立柱内设置储油舱存储天然气凝析油,解决凝析油存储外输问题。平台采用成熟系统系统集成,运动性能优良,海上施工风险可控,未来有望成为一种新的深水油气田开发平台型式。
英文摘要:
      A deepwater multi-functional dry tree semi-submersible platform, adaptd to the environmental conditions of the South China Sea, has been developed for gas condensate fields. The platform has excellent motion performance with the following functions: dry tree development, tie back subsea wellhead, oil and gas production processing, condensate oil storage and well drilling and workover. The platform consists of topside, hull, slender flexible connection structure, box heave plate, TTR riser system and mooring system. The slender flexible connection structure is used to connect the main hull and box heave plate. The box heave plate adopts box-type structure, and withstands the working draft pressure. The platform can realize the integral wet or dry tow. The platform is easy for installation and the slender flexible connection structure can be replaced in service. An oil storage tank is located in the platform column to store gas condensate. The platform adopts existing mature technology integration and has excellent motion performance with low installation risk. It can become a new type of deepwater dry tree development platform in the future.
