摘　　要：通过干扰井群理论公式法、群孔涌水量减少系数法及修正系数法确定宜黄岭下热田自然边界条件下及探矿权范围内可开采量为1774.96m^(3)/d(其中探明级为1384.41m^(3)/d,推断级为390.55m^(3)/d),地热水水温28.0℃-37.0℃。地热流体年开采累计可利用的热能量5.65×10^(7)MJ,与之相当的年节煤量为1927.87t。初步摸清宜黄县岭下地热田分布规律及资源量,为该地热田地热资源的合理开发利用提供科学依据。Based on the disturbance well group theoretical formula method,reduction coefficient method of water inflow of hole group and correction coefficient method,it is determined that under the natural boundary condition of YiHuang LingXia hot field and within the scope of exploration right,the recoverable amount is 1774.96 m^(3)/d (including 1384.41 m/d of proved level and 390.55 m^(3)/d of inferred level),and the water temperature of geothermal water is 28.0~37.0℃.The cumulative usable thermal energy of geothermal fluid mining is 5.65×10^(7)MJ,which is equivalent to the annual coal saving of 1927.87 tons.The distribution law and resource quantity of Lingxia geothermal field in Yihuang County are preliminarily found out,which provides scientific basis for the rational development and utilization of geothermal field heat resources.
