摘要
In order to study the nature of gas hydrate in porous media,the formation and dissociation processes of methane hydrate in loess were investigated.Five cooling rates were applied to form methane hydrate.The nucleation times of methane hydrate formation at each cooling rate were measured for comparison.The experimental results show that cooling rate is a significant factor affecting the nucleation of methane hydrate and gas conversion.Under the same initial conditions,the faster the cooling rate,the shorter the nucleation time,and the lower the methane gas conversion.Five dissociating temperatures were applied to conduct the dissociation experiment of methane hydrate formed in loess.The experimental results indicated that the temperature evidently controlled the dissociation of methane hydrate in loess and the higher the dissociating temperature,the faster the dissociating rates of methane hydrate.
