Abstract将多孔介质中天然气水合物在热力作用下的分解过程看作一个移动边界问题,在求解等温边界条件下水合物地层中分解区和未分解区(水合物区)温度场的基础上,推导出热力法开采水合物过程中开采热效率(用于水合物分解的热量与输入热量之比)和能量效率(开采所得甲烷气体的总热值与输入能量之比)的解析表达式.在相同水合物地层条件下,对比注入热盐水(采用NaCl溶液)和热水两种开采方法,得出热盐水中盐的浓度(简称盐度)对开采热效率等的影响.计算结果表明,采用热盐水开采热效率一般在40%~70%.在开采温度300~450 K、盐度0~15%的条件下,热力法开采水合物的能量效率在7.4%~11.3%之间.
