针对海上伴生气资源利用率低、传统回收技术经济性不足的问题，提出一种可移动自升式伴生气液化回收平台方案。基于渤海某油田实际工况，系统研究了平台的总体布局、液化工艺优化、LNG储运与外输等关键技术，并创新性提出桁架式软管外输方案与混合供电策略。研究表明，采用C型独立液货舱与单级混合制冷剂液化工艺（SMR）的组合方案，可降低设备重量与能耗；通过桁架输送臂实现LNG外输，可适应恶劣海况并减少运营成本。该研究为中小型边际油田伴生气高效回收提供了经济可行的技术路径，具有显著的环保与经济效益。
This paper proposes a scheme for a movable self elevating associated gas liquefaction and recovery platform to address the problems of low utilization rate of offshore associated gas resources and insufficient economic efficiency of traditional recovery technologies. Based on the actual working conditions of the oilfield in Bohai Sea, the overall layout of the platform, optimization of liquefaction process, LNG storage and transportation, and other key technologies were systematically studied, and innovative truss type hose export schemes and hybrid power supply strategies were proposed. Research has shown that the combination of C-type independent cargo tanks and single-stage mixed refrigerant liquefaction (SMR) can reduce equipment weight and energy consumption; LNG export can be achieved through truss conveying arms, which can adapt to harsh sea conditions and reduce operating costs. This design provides an economically feasible technical path for efficient recovery of associated gas in small and medium-sized marginal oil fields, with significant environmental and economic benefits.
