摘要
天然气水合物作为清洁高效的替代能源,其商业化开采已提上日程。日本与中国相继对海域天然气水合物进行了试采,试采的主要技术均为降压法和化学药剂注入法。论文基于流动安全保障技术,结合我国南海神狐海域开采的资料,对井下降压加热与气液分离,双泵降压两种试采技术方案进行深入分析,为后续海域天然气水合物商业化开采的设计与生产提供参考和借鉴,对增强可持续发展能力、推进绿色清洁能源发展具有重要意义。
Natural gas hydrate emerges as a sustainable and alternative clean energy source.Large scale commercial production of marine gas hydrate has become more feasible following recent offshore natural gas hydrate production trials in Japan(2013)and China(2017).At present,common practices for marine natural gas hydrate production trials involve the implementation of depressurization and chemical injection.This paper demonstrates the importance of flow assurance for marine natural gas hydrate production through the discussion of two natural gas hydrate production methods,which are the downhole depressurization&separation and the dual pump multiphase transport.It provides technical reference for future design and construction of marine natural gas hydrate production facilities globally.
