气体水合物的研究和应用现状

Gas Hydrates Research and Application Progress

气体水合物的研究已经成为人们关注的焦点,其无论是作为能源资源还是基于水合物的应用技术研究,都对人类的发展具有重要意义。本文从气体水合物的相平衡热力学、生成动力学、分解动力学、天然气水合物资源勘探开发、管道水合物的预防和抑制、基于水合物的应用技术开发等方面,综述水合物的研究现状,并对未来气体水合物的研究和发展方向进行了展望。认为多孔体系水合物相平衡、水合物的快速生成机理、沉积物中水合物的分解动力学、水合物抑制机理、地层水合物结构和物性等将是今后气体水合物研究迫切需要解决的技术瓶颈。

Research on gas hydrates had become a focus topic. Whether it was used as an energy resource or hydrate-based application technology, it was of great significance to human development. In this paper, the research progress of the phase equilibrium thermodynamic of gas hydrates, the formation kinetic of gas hydrates, the decomposition kinetic of gas hydrates, natural gas hydrate resources exploration and development, prevention and inhibition of hydrates in oil and gases pipeline, and hydrate-based application technologies development were summarized, the research and development of gas hydrates in the future were also discussed. The results showed that the phase equilibrium of gas hydrates in porous, the rapid formation mechanism of gas hydrates, the decomposition kinetics of hydrates in sediment, the inhibition mechanism of gas hydrate, the structure and physical properties of gas hydrates in sediment that would be urgently resolved in the future.
