摘　　要： 测量并计算了台成天然气水合物的形成条件,结果表明,温度越高,水合物相平衡压力越高,而且压力的增加率越大.在水合物相平衡测量基础上利用水合物形成实验装置,在定压条件下对表面活性剂体系水合物的形成过程和水合物的储气质量进行了实验研究,实验结果表明,活性剂对水合物的形成具有显著的促进作用,提高了水合物的储气密度.在3.86MPa、274.05K条件下,天然气水合物的储气量达159. Hydrate formation conditions of a synthetic natural gas were measured and calculated. The experimental and calculated results showed that the higher the temperature, the higher the equilibrium pressure, and the greater the slope of increasing pressure. Hydrate formation progress and gas storage capacity of the hydrate were studied experimentally in aqueous surfactant solutions using the hydrate formation experimental apparatus, based on the measurements of hydrate formation conditions. The experimental results showed that surfactant was a promoter, and hydrate storage capacity was improved greatly with the presence of surfactant. Hydrate storage capacity achieved 159 under the conditions of 3.86 MPa and 274.05 K.
