Evaluation Of The Beginning Of The Loop Basin Geothermal Geological Characteristics And Geothermal Resources In The Nei Meng Gu Autonomous Region

In this paper after the Loop basin basis of geological data, at home and abroad alarge number of geothermal geological data analysis and field geological survey,geophysical survey and other work basis, basin geological characteristics ofgeothermal geological features and geothermal systems carry out a morecomprehensive study, the finalcomprehensive geological and geophysical results ofanalysis and forecast of geothermal exploration well location of, and demonstrated theuse of actual drilling of the study area, the preliminary evaluation of geothermalresources.Geothermal wells depth of2012m. Geothermal reservoir of the geothermal wellson the Tertiary sandstones of the Miocene, bottom temperature78℃, the geothermalgradient of3.5-3.9℃/100m water level depth of10.50m, by the pumping testdrawdown54.2m inflow2256m~3/d, the water temperature of57℃, the projecteddrawdown is80m when Bay water up to3788m~3/d. Use of water temperature15℃meter, the annual release of22.49×1010KJ heat, equivalent to08,970tonsDongsheng coal incomplete combustion heat release (25×106J/kg).Geothermal wells of hot water total dissolved solids content of47mg/L CL-Natype water. The content of silicic acid in the water reached the naming standards ofthe medical hot mineral water, water, bromine, iodine, boron content reaches orexceeds the concentration of mineral water and medical value concentration, mayname the neutral sodium chloride type containing bromine, iodine, boron siliconwarm-medical mineral water. In LR1geothermal well water detected in F, Sr, Ba andFe, of Zn, Se,Co., V, Mo,Mn, Ni and Cu, Ai and other trace elements beneficial tohuman body, with high medical value. Can be used directly for medical care, bath.The well mineralized higher basically reached the industrial mention salt standard,therefore, comprehensive development area to geothermal resources with a broadprospect.
