| 摘 要： | 沉积物水合物在热源周围的分解范围是水合物热开采以及相关灾害分析的重要基础数据.该文针对平面内边界有恒温热源的水合物热分解范围问题进行了理论分析和四氢呋喃水合物沉积物模型实验,并将两者结果进行了对比.结果表明:沉积物水合物最大分解范围主要取决于热源与环境温度的温差;热源周围水合物热分解最大范围的理论值与实验值接近,误差小于5%.

| Abstract: | The thermal dissociation scope of gas hydrate in deposit around heat conductor is very important for either gas hydrate exploitation or related hazard prevention.Maximum dissociation scope based on planar heat dissociation under the boundary condition of constant temperature is obtained and compared with that obtained in heat dissociation experiments of THF hydrate in deposit in this paper.It is shown that the maximum dissociation scope is determined by the difference between the temperatures of heat source... |
