| 摘 要： | 通过实验研究了利用模拟瓦斯气体在井下温度和中高压的条件下合成瓦斯水合物。采用以实验为主，理论分析和计算机模拟相结合的研究方法，目的在于找出压力、温度及表面活性剂对水合物生成过程的影响。在井下温度和中高压的条件下，采用合适的表面活性剂及一定配比成功合成了瓦斯水合物。得出的结论是：表面活性剂在溶液中形成胶束后很大程度上可增加瓦斯气体的溶解度；与压力相比。温度对水合物的影响更重要：在气一液界面先合成的水合物有利于剩余水合物的合成。

| Abstract: | The paper introduces the formation of imitative gas hydrate at the temperature in main shaft and moderate high pressure.The research dominated by experiment technique ways and combined with theoretical analysis and computer imitating is mainly directed at finding out the influence of the pressure,temperature and surfactants on the formation process of hydrate.In the condition of main shaft temperature and the moderate to high pressure,the success of the hydrate formation is in term of proper surfactants and the certain proportion.Some conclusions could be reached.Surfactants can enlarge the solubility of methane which form micelles in the solution;Compared with the pressure,the effect of the temperature on the hydrate is more significant;the hydrate in the gas-liquid interface benefits the other one. |
