Geothermal Resource Development in Tianjin of China

Abstract

In low carbon economy, new energy, especially the development and utilization of renewable energy and energy saving and emission reduction are very important. Tianjin have favorable conditions to do the work. Geothermal exploration begin in 1970’s in Tianjin. 8 geothermal field have been found and It has rich geothermal resources. Low medium temperature geothermal resource potential reserves of 844.617×109m3, equivalent to the total heat resources 6.6×109 tons of standard coal. The proven geothermal water recoverable reserves of 68.57×106 m3/a. Geothermal markets have been broadened and made great progresses with the economic rapid developing processes and growing need for geothermal resource in Tianjin. 474 geothermal wells have been drilling and geothermal space heating has reached 20 million m2 in 2013. almost a 20% increase over the 2010 data, growing at a rate of 5,0% annually. Geothermal reinjection test carried out since 1996. Injection ratio of single well reach 100% in karst reservoir and 50-80% in porosity reservoir. The total injection ratio reach 34% of production.
