摘要
2015年下半年,在西安市西咸新区泾河新城成功钻凿了一口地热井,查明了该地区的地层情况及热储条件。地热井成井水温86℃,通过大、中、小落程进行放水实验,评价单井可开采量为213.51m3/h;通过计算求出开采权益保护范围半径1816.14m,开采影响区直径为3632.28m;该地热井井深2750m,开采层为新近系蓝田灞河组下部,高陵群,古近系地层。
In the second half of2015,a geothermal well was drilled successfully in Jinghe Xincheng,Xixian New Area,Xi'an City,and the formation condition and geothermal reservoir conditions in this area were found out.The water temperature of the geothermal well was86℃.Through the experiment of large,medium and small drop,the recoverable capacity of single well is estimated to be213.51m3/h,through calculation,the radius of protection range of mining rights and interests is1816.14m,and the diameter of the mining influence area is3632.28m.The depth of the geothermal well is2750m,and the exploitation layer is the lower part of the Neogene System Lantian Bahe Group,the Gaoling Group and the Paleogene System.
