Tianjin is the earliest city of geothermal exploration,development and utilization in China,but large-scale extraction of geothermal water has caused a rapid decline of water level and increased mining costs in the geothermal field,especially in the urban city.In order to protect geothermal resources,the method of geothermal single well integrated or rebuild recharge wells to build production reinjection doublet systems,which can effectively alleviate the drawdown rate.In this paper,the merits,drawbacks and applicability of two mode geothermal resources integrationare mentioned.Some economic returns and contribution to societ yand environmental protection are also discussed though two completed practical engineering of different geothermal resources integration modes.
