Field Experiment Study on the Energy Storage in Brackish Aquifers

Abstract

Field Experiment on the Energy Storage in Brackish Aquifers is the key measure to explore in the characteristics of this particular energy storage in aquifer, but now the key measure of the relevant field experiment study in domestic of China is still in a state of blank. This paper should be based on the consequence of site survey, and carry out the construction work of pumping/injection wells and observation wells. Kept other factors in the same premise, through changed the temperature of water injection, the experiment of heat storage and cold storage was conducted. In conclusion, as the coefficient of hydraulic conductivity having a same change with the geo-temperature in brackish aquifers when the hydrogeology condition of brackish aquifers remains the same. When the experiment of heat storage was over, the water level amplitude of injection well 1 was 2.5 m. Meanwhile, at the end of the experiment of cold storage, the water level amplitude rose to 3.1 m.
