合成瓦斯水合物诱导时间的研究

Research on inducement time of formation of gas hydrate

通过研究利用模拟瓦斯合成瓦斯水合物的诱导时间,以寻找缩短诱导时间的主要因素.结果表明:分别使用SDS(十二烷基硫酸钠),SDBS(十二烷基苯磺酸钠)及吐温-80等表面活性剂可在煤矿井下温度和中高压的条件下生成瓦斯水合物,同时使用已融化的水合物进行重复实验可显著缩短诱导时间;而且温度越高,诱导时间越长.

Investigated inducement time of formation of imitative gas hydrate in order to shorten inducement time. In the experiment the gas hydrate can be formed at the well temperature and moderate high pressure by using SDS, SDBS and tween-80 surfactants respectively. The repetition experiment using the gas hydrate of melted can shorten inducement time obviously. Moreover, the higher the temperature is, the longer the inducement time is.
