瓦斯水合物形成过程的电阻特性
Resistance characteristic of gas hydrate formation process
摘要
Abstract
This paper is driven by the need for investigating the law governing the dynamics function and saturation distribution in the forming process of gas hydrate.The investigation involves using gas hydrate impedance testing experiment device to perform the kinetics experiments of mine gas hydrate under the condition of adding different concentrations of SDS (0,500 mg/L) solution and NaCl(3％,6％ and 9％) solution composite systems;and calculating gas hydrate growth rate and saturation using mathematical models.The experiment demonstrates that resistance change law can define the forming characteristic of hydrate;resistance change trend underlies the main concentration of gas hydrate in the 4 groups of experimental systems in the upper and middle layers of the experimental kettle;and an increase in NaCl concentration is followed by a decreasing trend in the growth rate and saturation of gas hydrate.NaCl-SDS mixed solution system enables an increased hydrate growth rate and an increased saturation of gas hydrate.关键词
