| 摘 要： | 通过对甲烷和乙烯混合气体在4个电导率大小不相同的水样中进行分离对比实验,考察了水溶液的电导率对气-水合物的相平衡、生成速率的影响。结果发现,电导率越小,反应速率越大,乙烯在气相和水合物相中的分配系数越大,利于水合物的生成和水合物晶体的稳定,由此推论,通过测定电导率可初步判断自然界中天然气水合物藏的特点。

| Abstract: | The effect of solution conductance on vapor-hydrate phase equilibrium and the hydrate formation rate were studied. It can be found that the hydrate formation rate and partition coefficient of C2H4 between vapor and hydrate phase increase with the decrease of conductance, which is beneficial to formation and stability of hydrates and the separation of CH4-C2H4. It can be concluded that the characteristics of gas-hydrate reservoir will be obtained through determining conductance. |
