Abstract
Geothermal reinjection has experienced for some 30 years in Beijing. Various reinjection tests were stated in small scale at the beginning. At present, geothermal reinjection in productive scale has been carried out in 6 couple of wells. The annual reinjection quantity is 1.322 M m3. It equals 56.6% annual production yield. Reinjection raises reservoir pressure. There are obvious efficiency on resources, economy and environment aspects. The mechanism of the reinjection has been studied during the progress of the reinjection.
