Abstract:In order to solve problems occurred in development and utilization of geothermal resource, such as falling water levels, thermal fluid discharge and chemical pollution caused by thermal pollution, through study on geothermal tailwater recharge, it is regarded that artificial back fill source must be done when exploiting deep underground hot water resource. Geothermal tailwater recharge has been carried out in Dezhou, Dongying and Ji'nan in Shandong province. An remarkable effect has been gained.
