| 摘 要： | 利用全透明蓝宝石水合物静力学实验装置,采用“压力搜索法”,分别测定了5种凝析气的水合物生成条件,实验体系包括纯水、地层水以及含醇的水溶液和地层水溶液,共9个体系,58个数据点.考察了气油比对凝析气水合物生成条件的影响以及电解质和醇类抑制剂对凝析气水合物生成的抑制作用.实验温度范围为273.35～293.75K,压力范围为0.6～12MPa.并利用Chen和Guo提出的水合物生成条件预测模型对所测数据进行了计算,结果与实验数据吻合得较好,表明该模型能够较好地预测凝析气水合物的生成条件.

| Abstract: | The hydrate formation conditions of five gas condensates in pure water,brine and aqueous alcohol solution were measured using“pressure search” method.The experimental temperature range was 273·35~293·75K and the pressure range was 0·6~12MPa.The effect of gas/oil ratio(GOR) and the content of the electrolyte and alcohol on the hydrate formation was studied systemstically.The experimental data were compared with the results predicted with the model reported by the authors in former paper and it was shown that this model could predict the hydrate formation condition for the gas condensates satifatorily. |
