摘　　要：水合储气技术具有高效、安全、经济的优点,但存在气-液-热传输效率低、水合反应慢等缺点。从气液迁移、水合相变和热量转移等方面阐述了气体水合物生成机理,分析了搅拌、鼓泡、喷雾、射流、超重力等动态强化技术的利弊。基于静态储气理念,从传质角度综述了水合储气介质(水)表面活性改性、物理分散改性等方法在加速水合物生成中的应用。在节能减排背景下,静态水合强化技术更具发展前景,对水合储气技术工业化应用具有重要参考价值。Hydrated gas storage technology has the advantages of high efficiency,safety and low cost,but the gas-liquid-heat transfer efficiency is low and hydration reaction rate is sluggish.Mechanism of gas hydrate formation was discussed from the perspectives of gas-liquid migration,hydration phase transition and heat transfer. Advantages and disadvantages of dynamic intensification technologies such as stirring,bubbling,spraying,jetting and supergravity were analyzed. Based on the static gas storage theory,surface activity modification and physical dispersion modification of hydrate gas storage medium in accelerating the formation of hydrates was reviewed. In the context of energy saving and emission reduction,static hydration enhancement technology shows huge development prospects,which provides important reference value for the industrial applications.
