Abstract
Since the 18th CPC National Congress, the CPC Central Committee has given high priority to promoting ecological progress and made plans to win the battle against pollution. However, shandong province is rich in geothermal resources. Based on the analysis of geothermal geology and geothermal water pressure, water temperature and water quality in Dezhou city, this paper focuses on the technical method of geothermal tail water recharge in sandstone heat storage. At the same time, the environmental geological problems caused by the continuous exploitation of geothermal water, such as falling funnel, resource exhaustion, ground subsidence and thermal pollution, are put forward. According to the development and utilization of geothermal resources in Dezhou, the "Dezhou model" of geothermal utilization has been built, a demonstration project of recharging tail water from sandstone heat storage has been established, and suggestions on environmental protection such as strengthening dynamic monitoring of science and technology pipe mines and geothermal Wells have been put forward.
