| 摘 要： | 基于悬浮气泡表面生成气体水合物的高压可视化实验装置,分析探讨了系统压力、温度、水质因素对天然气水合物的成核和生长规律的影响。研究结果表明,随着反应温度的降低和反应压力的增大,诱导时间和生长时间呈现出缩减的趋势,气泡表面水合物逐渐由粗糙变得光滑;蒸馏水形成的水合物比较规则、密实,而纯净水形成的水合物略显凌乱、松散;相同实验条件下,蒸馏水生成水合物的诱导时间和生长时间较短。

| Abstract: | Based on a set of high-pressure visual experiment device built for the investigation of the natural gas hydrates crystallization and growth on the suspended gas bubble surface, the in- fluence factors such as pressure, temperature, water quality were analyzed and discussed. The results showed that the higher pressure or the lower temperature resulted in the less induction time and growth time, which led to surface changing from rough to smooth. The surface of hy- drate film in distilled water is smoother and tidier than that in pure water. Under the same exper- imental conditions, the hydrate film in distilled water grew faster than that in pure water. |
