Monitoring and Resources Evaluation of the Geothermal Fields in Tianjin

Abstract

Geothermal monitoring was started in Tianjin in the 1980s, in order to better develop and utilize the geothermal fields. After more than 20 years of continuous improvement, the geothermal dynamic monitoring system has been set up in Tianjin. Meanwhile, the technical criterion monitoring of low-medium temperature geothermal fields in Tianjin was compiled in 2006. Aiming at the difficulties of measurement, cost recovery and administrative monitoring, research and development of an intelligent management Net PC system for geothermal wells was carried out. This system can make a real-time monitoring for every developer, raising the ability and the level of geothermal administration to a new level. It is very helpful for scientific planning and management of the geothermal development and utilization in Tianjin. Based on the continuous geothermal monitoring for many yeas, a new evaluation of the geothermal resources in the plain area of Tianjin has been carried out from 2005 to 2007. The optimization plans are put forward for future geothermal development．
