| Abstract |
As renewable resource, geothermal energy is very significant to the development of the economy of the country. Re-injection of the geothermal fluids after utilization is the main means to keep the resource usable. In Tianjin area, the re-injection test and research in Sandstone re-injection has continued more than 20 years, but the re-injection can’t reach the industrial level. In this report, we discussed reinjection issues from different perspectives including: reservoir configuration, aquifer characteristic, re-injection fluids temperature, drilling technique, and methods. |
