| 摘 要： | 根据砂岩孔隙型热储地热流体回灌试验中不同尾水温度与回灌量、回灌水位之间的关系，研究了相同回灌量条件下尾水温度对回灌效果的影响，并通过消除回灌尾水温度对井筒存储效应的影响，将回灌时水位升幅的观测值校正为同一温度下的真实水位升幅，从而对不同温度尾水回灌的渗透性能进行了分析。

| Abstract: | According to the relationships between different tail water temperatures and reinjection volume and water level in reinjection experiments of sandstone porous type geothermal reservoirs, the influence of temperature to reinjection under the conditions of the same reinjection volume has been studied. Through eliminating the influence of temperature to the wellbore storage, converting the observation values of the water level to the real level in the same temperature, the permeability of the tail water reinjection in different temperatures has been analyzed. |
