摘　　要：文章通过对孔隙型热储层地热流体回灌试验中回灌量与液柱压力、流体温度相互关系等方面分析和探讨,认为其主要影响因素为热储层物质结构、水文地质特征、回灌水温度、成井工艺、回灌与开采井间的距离、回灌方式等条件。As renewable resource, geothermal resources are of important significance in the development of economy of the country, and reinjection is the main means to keep the renewable development of geothermal resources. Although the reinjection test and research of the geothermal reservoir of porous type has been carried out for about 20 years, the reinjection has not reached the industrial level. In this paper, we discuss such factors as reservoir configuration, aquifer characteristics, reiniection temperature,reinjeetion methods, etc.
