| 英文摘要 | The low-medium temperature geothermal resources, as a clean and alternative energy source, are widespread in North China. The hydrothermal system which is related to active faults is an important component of low-medium temperature geothermal system. Based on the data of high precision gravity measurement, microtremor survey and borehole temperature logging, we discussed the characteristics of the hydrothermal system in Nankou-Sunhe fault zone, including heat source, channel, reservoir and cap rock. The negative gravity anomaly reveals that the area of buried Yanshanian granodiorite-adamellite mass is about 14. 3 similar to 23. 8 km(2). The heat production of the buried rock is 1. 65 similar to 3. 14 mu W center dot m(-3). Thus, the buried mass rock is not enough to provide additional heat to the geothermal system. The width of gravity gradient belt of Nankou-Sunhe fault is about 500 similar to 800 m. The fault zone cut through the carbonate reservoir of Wumishan Formation of Jixian System and is characterized by strong hydrothermal activity. The fault zone is considered as an important channel of deep geothermal water. The Quaternary and Jurassic volcanic rocks, located in the southwest of the fault zone, constitute the cap rocks of thermal reservoir. The microtremor survey results show that the Jurassic volcanic rocks have a maximum thickness of around 1500 m. Based on the analysis of four factors of geothermal system, i.e., heat source, channel, reservoir, and cap, the genetic model of the geothermal system of Nankou-Sunhe fault can be considered a conduction and convection mixed thermal system. The precipitation from the northwest mountainous area of Beijing is heated by the strata when it moves from surface to the deep ground. The hot water carried by high pressure through the Nankou-Sunhe fault to the dolomite strata and formed hydrothermal system with good geothermal conditions and economic production. |
