【摘要】 海南省乐东县龙沐湾地热田属于隐伏小型中低温地热田,地热田面积约12 km2,呈南北半月形带状展布,该地热田内3口地热井为32℃～42℃。通过对地热田内地热井的水化学资料分析得出,地热田水化学类型以HCO3-Na·Ca型为主,地热流体水化学组分基本处于稳定状态。同时对地热流体质量评价,将地热田地热流体命名为重碳酸钠钙型硅温水,可作饮用天然矿泉水,不宜作生活饮用水、渔业用水和农业灌溉,地热流体不具有腐蚀性且通过碳酸钙结垢趋势判断为不结垢。更多还原

【Abstract】 TheLongmuwan geothermal field in Ledong County,Hainan Province belongs to the concealed small medium-low temperature geothermal field. The geothermal field is about 12 km2,which is distributed in the north-south half-moon shape. The geothermal wells in the geothermal field are 32 ° ～ 42 ° C. According to the analysis of water chemistry data of geothermal wells in geothermal field,the water chemistry type of geothermal field is mainlyHCO3-Na·Ca type,and the hydrochemical composition of geothermal fluid is basically stable. At the same time,the geothermal fluid quality evaluation,the geothermal field geothermal fluid named wet sodium bicarbonate type silicon warm water,can be used for drinking natural mineral water,not suitable for drinking water,fishery water and agricultural irrigation,the geothermal fluid is not corrosive and is judged to be non-fouling by the tendency of calcium carbonate scaling.更多还原
