摘要
传统深海天然气田开发工程模式是通过铺设海底管道将天然气田产物输送至陆地,由于受水深、海底地形、技术可行性及天然气田经济效益等多种因素的制约,限制了其在深海天然气田开发中的应用。FLNG装置或CNG船与海上天然气生产设施组合为新型的深海天然气田开发工程模式,以投资相对较低、建设周期短、灵活机动性好及目标市场可选范围广等优点备受关注。通过调研FLNG装置及CNG船的技术发展概况,详细分析了三种适合深海天然气田开发工程模式的特点,对比总结出深海天然气田开发工程模式优选的参考条件。以FLNG装置及CNG船为代表的深海天然气田新型开发技术将打破传统深海天然气田开发工程模式,成为深海油气开发技术发展的重要里程碑。
Traditional deep sea gas field development engineering mode is to lay submarine pipelines for transporting products from gas field to the land. Such factors as water depth, submarine topography, technical feasibility and economic benefits may limit its application in deepwater gas field development. Combination of floating liquefied natural gas(FLNG) facility or compressed natural gas(CNG) ship andoffshore gas production facilities can be used as new type of marine gas field development engineering mode and industry insiders are giving more and more importance and attention to such new type of development mode due to its such advantages as relatively low investment, short construction period, good maneuverability and wide range of target market. Reviewed is the general situation of FLNG facility and CNG ship technology development, analyzed are characteristics of three kinds of models suitable for deep gas field development and summarized are reference conditions for selection and optimization of deep sea gas field development models. The new deepwater gas field development technology represented by FLNG facility and CNG ship will certainly break traditional deepwater gas field development engineering model and become an important milestone in the development of offshore gas field development technology.
