Geothermal Industry Development Present Situation And The Future Research In The Guanzhong Area

Guanzhong is an important industrial base in Shaanxi.In recent years,a number of Guanzhong City Group,especially in Xi'an,has occupied consecutive high levels about haze in our country.About the causes of haze in Guanzhong area,human factors caused by coal and other pollutant emissions are the key,which have coused serious threat for the survival and development of human society.With the introduction of "13th Five-Year" geothermal development planning and hot water of geothermal heating have increased new area of 45 million m3,so to find out the real situation,improve the energy structure,accelerate the development of geothermal energy industry in Guanzhong area are urgent.In this paper,the geothermal energy industry development situation of Guanzhong City Group is our main research object.through the multi-angle analysis and comparison of geothermal heating way about shallow geothermal resources,the deep hot water type geothermal resources and non disturbed geothermal heating system,industry development present situation,economic efficiency,the core technology and the development prospect provide the scientific basis of sustainable development and utilization for geothermal resources in Guanzhong area for the city.From the Qinling Mountains to the north,TDS increased gradually,and underground hot water experienced a process from the opening modern leaching water,mixed water between half open semi-enclosed modern leaching water and the paleo leaching water to sealed remnants of sedimentary water.Deep reservoir temperature is about 110 degrees,and the shallow heat reservoir temperature in the Piedmont region of Qinling Mountains is 80 degrees.circulation depth of the hot water is 1037~3687m.From the underground hot water distribution of ?value,we can see that water samples of Xianyang,Xi'an are from atmospheric precipitation,and there is oxygen drift.And it Shows that reservoir conditions of Xi'an,Xianyang city are relatively closed,and water rock reaction in Xianyang is more intense.Xi'an City 198 in deep geothermal well over the years the water level drops greatly,control after mining,water is still in the gentle decline in most areas of groundwater depth in the next few years will be more down to 200 m.As the strategic objective of Shaanxi province water heat type geothermal heating and sustainable development to achieve "13th Five-Year" period,the establishment of a mining irrigation system imminent geothermal exploitation in Xi'an area.At present,the utilization efficiency of the geothermal industry in Guanzhong area is limited,and the awareness is not high.most of the underground hot water has very good health care effect,so tourism balneation industry should continue to develop vigorously.Now the total area of heating proportion of geothermal heating is very low.So the new housing estate should be based on the geographical and regional geological characteristics to actively choose suitable geothermal heating.The heat pump system of shallow geothermal energy,Deep in the water hot type geothermal well irrigation system,and non disturbed geothermal heating system are better than traditional fossil energy supply system in comprehensive benefit,and technology also meets the basic promotion requirements.By comparison,in the initial investment,operation cost,occupation area,environmental geological problems,and durable years and so on,there are differences,advantages and disadvantages.However,deep in the guanzhong region water heat storage of the geothermal resources are advantaged.Large water volume,high water temperature,water quality and abundant reserves,and these advantages are rare in our country.So we should break the barriers of thinking,solve the problem of concept,perfect local laws and regulations,improve the public awareness,make full use of hydrothermal type geothermal resources,based on sustainable development and make the best of development.As soon as possible in the proportion of Guanzhong City Group to improve the hydrothermal type of geothermal,and let the underground thermal energy as much as possible to replace the fossil energy heating,that is to say,use geothermal to replace coal.And letting Guanzhong geothermal resources gived by nature play their role in dealing with pollution and reducing haze.
