Study on Optimal Reinjection Strategy of Geothermal Field: A Case Study from Tianjin, North China

Abstract:

Based on general characteristics of the Wumishan reservoir, the hydrogeology model is founded. And the problem of no more space for adding reinjection wells, the mathematical descriptions and influent of hydrothermal transportation, thermal break-through and the flow feed path with the different fracture zone were emphasied. According to simulat ion of the different models, a new ideal strategy about the reinjection wells was put forward, which can be set in the periphery of geothermal zone. And more heat can be extracted from the reservoir rocks through the reinjection activities. The pressure and temperature field of the reservoir will be controlled even though the injected cool water moves forward to the product zone, the water level and temperature field can be more stable with the reinjection models.
