摘　　要：采用水合物法进行天然气储运是目前国内外正着力开发的一种新型天然气储运技术,水合物在不同温度压力条件下的稳定性及其分解特性是该技术应用发展的重要基础。奇异自保护效应的存在表明水合物在特定的低温温区内具有良好的稳定性,这也为开展水合物法储运天然气提供了有力的理论和试验依据。综述了气体水合物自保护效应的研究历史及其应用于天然气储运的工程应用,指出了自保护效应研究中依然存在的困惑及发展水合物法储运天然气技术所面临的挑战。Storage and transportation of natural gas as hydrate was a developing novel technology, which based on the stability and dissociation characteristic of hydrates at different temperatures and pressures. The existence of anomalous self-preservation effect indicated that gas hydrates had favorable stability in specific low temperature range which provided powerful theoretical and experimental support for storage and transportation of natural gas as hydrate. The research progress in hydrate self-preservation effect and its application in storage and transportation of natural gas were summarized. Puzzles in study of self-preservation effect and challenges for developing the technology of storage and transportation of natural gas as hydrate were also pointed out.
