摘　　要：通过尝试运用回灌条件下单井开采权益保护半径的方法和热突破公式计算回灌条件下流体可开采量,形成了回灌条件下流体可开采量评价体系。并进行了实例计算,结果表明,随着回灌温度的增大,越不易于发生热突破,其流体可开采量也迅速增大。Under condition of geothermal reinjection,tried to use the method of the interests＇ protection radius of single well and the formula of thermal breakthrough time to calculate geothermal fluid exploitable reserve,this paper formed the assessment system of it. And a case study was carried out,the results shown,along with the more increase of reinjection temperature,the thermal breakthrough was the more difficult to be occurred and the geothermal fluid exploitable reserve also increased rapidly.
