摘　　要：洛阳龙门地热田位于洛阳断陷盆地西南部,依据地热地质资料,分析研究了龙门地热田边界、空间分布特征、形成机制、地球物理化学特征、地热水温度场、热储构造发育特征,同时对龙门地热田地热水的赋存、运移条件等进行了分析探讨。该地热田的形成受地质构造控制,属构造热储对流型地热田,草店断裂(F1)和魏湾断裂(F2)为龙门地热田的控热构造,伊河断层(F3)、朝阳—首阳山断层(F4)为地热田的导热、导水构造,寒武系灰岩为龙门地热田的热储层,上覆数百米的二叠系、三叠系砂岩、泥岩互层为该地热田热储层的盖层,龙门地热田地热水水温高达98.5℃,开发利用前景广阔。The Luoyang Longmen geothermal field is located in the southwestern part of the Luoyang fault basin.The formation conditions are strictly controlled by geological structures.It belongs to the convective geothermal field of structural thermal storage.The heat conduction and water conducting structure,∈3 is the thermal reservoir of the Longmen geothermal field,and the overlying hundreds of meters of P2 and T1+2 become its thermal reservoir cap layer.The discovery of the warm geothermal water(98.5℃)in the Longmen geothermal field provides broad prospects for the development and utilization of the geothermal field.Based on the geothermal exploration data over the years,starting from the analysis of the boundary,spatial distribution characteristics,and thermal storage structure development characteristics of the Longmen geothermal field,the paper analyzed and discussed the formation mechanism of the Longmen geothermal field,geophysics,geochemistry,geothermal water temperature field characteristics,geothermal water,storage and transportation conditions,etc.
