摘　　要：针对南海天然气水合物开发计划,研究其开发模式十分必要。荔湾3-1深水气田的地理位置与南海天然气水合物开发先导试验区相邻,环境条件相似,从2014年投产以来已成功运行多年,其开发模式值得借鉴。对荔湾3-1气田开发模式进行总结,结合南海天然气水合物采出气特点,设计出南海天然气水合物开发模式,对开发模式中所采用的生产设施和工艺处理流程的技术可行性进行评估,认为荔湾3-1气田开发模式可以作为未来南海天然气水合物商业化开发时考虑采用的一种方案,但受限于固定式平台安装水深的局限性和水合物的开采特点,此种开发模式对水合物采出气的采收率将会产生一定的影响。Regarding the development plan of natural gas hydrate in the South China Sea,it is necessary to study its development mode.The Liwan 3-1 deep water gasfield is located adjacent to the pilot test area of natural gas hydrate development in the South China Sea and has similar environmental conditions.It has been successfully operated for many years since it was put into production in 2014,and its development model is worth learning.The development model of the Liwan 3-1 Gasfield was summarized,combined with the characteristics of the gas produced by the South China Sea natural gas hydrate,the South China Sea natural gas hydrate development mode was designed,and the technical feasibility of the production facilities and process treatment processes used in the development mode was evaluated.The results show that the Liwan 3-1 Gasfield development mode can be considered as a plan for the commercial development of natural gas hydrates in the South China Sea in the future.However,due to the limitation of the installation depth of the fixed platform and the characteristics of hydrate production,this development mode will have a certain impact on the recovery rate of hydrate-produced gas.
