The Exploitation Dynamic and Sustainable Development of Geothermal Resource in Tianjin, China

Abstract

Tianjin, located at the east of Beijing, has abundant geothermal resources. There have been more than 300 geothermal wells by now. In 2007, the production is 2583.8×104m3, while the reinjection is 409.3×104m3, so the reinjection rate is 15.8%. For the positive exploitation of resources, governmental authorities supervise strictly by law in recent years. Meanwhile, new science and technology is taken as guider or driver and used in the economic construction and social development. So the technique level of exploitation and utilization has been improved and the resource utilization is transforming gradually from simple extensive pattern to circle intensivism pattern. Practice for years shows that：Only by strengthening the supervision, establishing the mechanism of technology innovation and achievement transformation on energy-saving and ejection-decreasing, the geothermal can develop healthily and sustainablely.
