摘　　要：为了强化甲烷水合物生成,满足工业生产天然气水合物的要求,利用定压鼓泡式反应器对甲烷水合物在冰浆体系中和水体系中的生成特性进行了对比实验研究。结果表明,冰浆体系中水合反应的诱导时间比水体系水合反应的诱导时间短;冰浆体系比水体系拥有更大的导热系数和反应热吸收能力,更有利于反应热的释放;十二烷基硫酸钠浓度改变的过程中,水体系中反应的诱导时间和水合物储气密度的变化比冰浆体系明显;冰浆体系可以提升水合物的储气密度,但是随着有利于水合物反应条件的增加,冰浆的提升效果会逐渐地减弱。In order to further strengthen the formation of methane hydrate,a comparative experimental study was carried out on the formation characteristics of methane hydrate in ice slurry system and water system by using a fixed-pressure bubble reactor.The results showed that the induction time of hydrate reaction in ice slurry system was shorter than that in water system hydrate reaction;ice slurry system had greater thermal conductivity and reaction thermal absorption capacity than water system,and was more conducive to the release of reactive heat;in the process of changing the concentration of sodium dodecyl sulfate,the change of induction time and gas density of water system was more obvious than that of ice slurry system;ice slurry system could improve the gas storage density of hydrate,but with the increase of hydrate reaction conditions,the effect of ice slurry gradually weakened.
