EXPLORATION AND DEVELOPMENT OF GEOTHERMAL RESOURCES IN TIANJIN
Tianjin is the first city in China where geothermal exploration has been carried out. Geothermal exploration was initialized in the 1970s. Tianjin is placed in geological tectonic unit I in the northern part of the China platform. Tectonic unit II comprise the Yansan mountainous compression zone and North China graben basin. Tectonic unit III consists of one uplift zone and two depression zones. Geothermal anomalies have been recognized in ten different areas. Seven geothermal fields have already been explored. Since the 1990s, the geothermal water has been used mainly for space heating. Geothermal water for heating covers an area of more than 12,000 x 103 m2 and delivers a volume of 100 x 103 of hot water for bathing in residential homes in Tianjin. The pressure of the geothermal reservoir is continuously dropping. For this reason geothermal reinjection is carried out in Tianjin.
