The natural heat discharge of the hot springs is >25.13×1013 J/a and the geothermal resources in the Wenquanpu area is >7.29×1014 J. The withdrawal rates of hot spring Nos.
In culturing the turtle(Amyda sinensis) by using geothermal energy resource, the temperature of the breeding water was controlled at 30℃±0 5~1℃; By using the water quality improving equipment which was consisted of regulating valve, water air injector and aerate pool, the dissolved oxygen in the breeding water was controlled above 3mg/L at most time, the endangering substance was also dilimited apparentlg, and the average weight improving and the survival rate of young turtle were improved greatly.
This article introduces the current state, corresponding problems and prospect of exploration and development of geothermal energy in Daqing area, and points out that effective development and exploitation of geothermal energy resource will definitely further sustainabledevelopment of Daqing area.
The article describes the forming types of terrestrial heat resources by the relation between the water-heat action and the geological condition,terrestrial geological characteristics,geological formational characteristics,terrestrial boundary condition,terrestrial heat system types and characteristics and its buried condition,heat storage water capability and so on and furthermore puts forward some suggestion on development of terrestrial heat resources in Luoyang Basin.
The article analyzes the main environmental issues caused by exploitation of terrestrial heat resources: earthquake, land subsidence, exhaustion of terrestrial heat resources, pollution by harmful composition of terrestrial heat water, heat pollution etc. , and proposed control recommendations.
These geothermal resources are subdivided into petrothermal and hydrothermal varieties representing thermal energy accumulated in rocks and groundwater fluids, respectively.
In Russia, geothermal resources are predominantly utilized for space heating in several cities and settlements of the Northern Caucasus and Kamchatka with a total population of 500?000.
The Big Pine field erupted only basalt lavas, some of which bear mantle xenoliths, whereas the Coso field erupted both basalt and rhyolite and is a major geothermal resource.
