中文摘要：

为验证煤层气注热开采的合理性，在实验室进行了考虑温度条件下煤层气的解吸渗流实验，实验结果表明，煤体在升温情况下煤层气解吸渗流量增加，注热开采煤层气具有合理性。根据实验结论，建立了含瓦斯煤层注热传热过程的数学模型，利用ANSYS软件进行了含瓦斯煤层注热温度场的数值模拟。数值模拟结果表明，注蒸汽后煤层的温度梯度改变，热量在井筒径向具有一定的热扩散位移。在热扩散范围内，煤层气更容易发生脱附解吸，有利于煤层气的产出。

英文摘要：

For validating rationality of heat injection in mining coal-bed gas, the experiment of desorption and seepage in non isothermal condition is done in laboratory. The results of experiment shows that the coal-bed gas increases under the condition of adding temperature and it＇s rational to heat injection in mining coal-bed gas. According to the experimental conclusions, the mathematic model of transferring heat process of coal-bed is given. ANSYS software is used to simulate the temperature field of coal-bed under the condition of horizontal well. The result of numerical simulation shows that the temperature gradient of coal-bed is changed after heat injection, and a displacement of thermal diffusion exists in radial direction of well. The produce of coal-bed gas increases and the desorption phenomenon is easier in the range of heat diffusion.
