可移动自安装无人井口平台南海适应性

Adaptation of Mobile Self-Installing Unmanned Wellhead Platform in South China Sea

由于边际油田产量低、依托设施远,采用常规导管架平台方式一直难以进行经济有效的开发。为解决这一问题,以南海北部湾某油田为目标油田,研究一种国内未曾应用的沉垫基础可移动自安装简易无人井口平台,采用数值模拟和规范校核方法对其进行总体方案研究、平台基础研究、升降系统装置选型、在位工况结构分析、拖航稳性分析和安装方案研究,分析该可移动自安装无人平台在南海北部湾的适应性,提供一种新型工程开发平台方案供工程开发方案选型参考。

Marginal oil field is difficult to develop because of low production and far distance from existing facilities.In order to solve this problem,a mobile self-installing unmanned wellhead platform which is not used in China is studied and one oilfield in Beibu Gulf of South China Sea is chosen as the target oilfield.The overall scheme,platform foundation,lifting system device selection,in-situ working condition structure analysis,towing stability and installation scheme are studied by the numerical simulation and standard verification methods.The adaptation of the mobile self-installing unmanned wellhead platform is analyzed and a new kind of engineering development plan can be provided for the reference of the chosen of engineering plans.
