根据中国海洋石油总公司“三新三化”及利用高科技降低海洋石油成本的精神,对涠洲11-4东区井口平台结构设计做了多方案比选、优化、简化等研究,最后采用了2腿3桩的新型简易平台结构,并使该结构设计付诸实施,从而打破了南海海域没有简易平台结构的历史,使平台用钢量大大减少,缩短了工程周期,降低了制造和安装成本,为海上边际油田开发闯出了一条新路。 According to the “three new, three modernizations” of CNOOC and the utilization of high technology to reduce the cost of offshore oil, CNNIC made a multi-plan comparison, optimization and simplification study on the wellhead platform structure design of 11-4 Eastern Weizhou, and finally adopted 2 legs and 3 piles of new simple platform structure, and make the structural design put into practice, thus breaking the South China Sea without a simple platform structure history, the platform greatly reduce the amount of steel, shorten the engineering cycle and reduce manufacturing and installation costs , For the development of maritime marginal oil to break a new road.
