摘要: 为研究天然气水合物注热水分解前缘的热作用影响,建立了考虑孔隙介质中水合物饱和度的分解前缘数学模型,并进行迭代分析求解;实验测温前缘和电阻前缘与数学模型拟合前缘较好的吻合,误差控制在8%以内;分析了注热水温度和速率对分解前缘的热作用影响:温度对分解前缘影响的误差不超过8.71%,较大流速对分解前缘影响误差为4.53%,在提高注入热水温度的同时以较大注入速率能减小对水合物分解前缘的热作用影响。Abstract: In order to study the gas hydrate thermal affection on hot water flooding dissociation frontal brim, the mathematical models of dissociation frontal brim counting hydrates saturation in the porous medium have been established and solved with an interactive method. The frontal brims of temperature probe and resistance from experiments fit well to the mathematical model matching and the errors are controlled less than 8%.The thermal factor infections of the hot water flooding temperatures and flooding rates on the dissociation frontal brim are analyzed.The errors of the temperature influence on the dissociation frontal brim are lesser than 8.71% and the influence errors of flooding rates on the dissociation frontal brim are 4.53%.The thermal infections on the hydrate dissociation frontal brim of hydrates can be lessened by rising injected hydrothermal temperatures with massive flowing rates.
