摘　　要：通过地质调查、物探工作、钻探工作,结合区域地质特征及CO2气藏形成的地质条件,对鹤壁市新区地热及CO2资源的赋存规律和成因进行了探讨。认为鹤壁矿区地处太行山前汤阴断陷盆地中部,其地下存在着奥陶系灰岩凸起的古潜山构造,这些凹陷中的相对凸起带是地下热水和CO2气藏的富集区。经分析该区地表以下无热异常,地热田属正常增温型地热区;CO2气藏为无机成因,是岩浆冷凝脱气和碳酸盐热解的共同作用。Through geological investigation, geophysical prospecting and drilling, combined with regional geological features and CO2 reservoir formation geological conditions discussed geotherm and CO2 resources hosting patterns and geneses in newly developed area of Hebi City. Considered that the Hebi mining area is situated in middle part of the Tangyin faulted basin, foreland of Taihang Mrs., protuberant Ordovician limestone buried hills are existed, these relatively raised zones are geothermal water and CO2 enrichment zones. After analyzed, no thermal anomaly below the surface was found, the geothermal field should belong to normal calefacient type, CO2 reservoir is inorganic genesis caused by collective actions of magma condensation degassing and carbonate pyrolysis.
