摘要
The research on the geothermal resources in Jingbo Lake graben of the Dun-Mi fault zone in Heilongjiang Province provides an example to acquire the formation rule of geothermal resources in the sag part of the large fracture zone. Jingbo Lake graben, the regional geological structure of which belongs to the northeast part of the Tan-Lu fault zone, expands in the form of the long strip. The results show that geological conditions of geotherm is very favourable. The integrated and calculated data show that the Jingbo Lake graben can be a large-scale geothermal field. The discovery of geothermal field of Jingbo Lake graben has the positive guidance for seeking out the geothermal resource in the Dun-Mi fault zone, Yi-Shu fault zone and Tan-Lu fault zone.
