Analysis on Reinjecting Modes in Geothermal Well of Porous Aquifer

Abstract:

In order to guide geothermal well reinjecting in the geothermal aquifers.4 different reinjected modes were adopted, analyzed the capacity and lasted time, the water level moved and the absorbing water index changed in accumulative reinjecting. Test results show that under the condition of the intermittent nature, Lasted time is short, reinjecting capacity is limited, in "wash well-reinjecting" mode, the volume of reinjected water is increased with the time of washing well, lasted time is longer, the volume of reinjected is greater, the volume decreased gradually in pressurized reinjected mode, the capacity of system has a great effect on operating the way. The research results have theoretical and practical significances for geothermal reinjecting well in porous aquifer.
