Chinese Abstract

通过室内模拟实验,分析了地热回灌堵塞形成机理,提出了消除各种堵塞因子的方法,研制了由抽水系统、水处理系统、回灌系统和监测系统四部分组成的地热回灌系统装置。通过采取过滤、加压、化学除垢等方法进行的地热尾水回灌试验,取得了历史最大回灌量,验证了渭河盆地新近系热储层具有回灌性,为关中城市群地热资源可持续开发利用提供了科学依据。

English Abstract

This study uses simulation experiments to analyze the clogging mechanism of geothermal reinjection. Methods to eliminate al types of clogging factor are proposed. The study presents a geothermal reinjection device with four parts:a pumping system, a water treatment system, a reinjection system, and a monitoring system. Geothermal tail-water reinjection tests using ifltering, compression, and chemical descaling obtain the largest injection quantity. The results verify that the geothermal reservoir in Neogene units in the Weihe basin can be reinjected, and provide a scientiifc basis for the sustainable development and utilization of geothermal resources in the urban agglomeration of Guanzhong.
