| 摘 要： | 通过对岸上襄郏断层的地热地质条件分析,表明该断层在研究区可分为三部分,且以南部地热异常最为明显;热储盖层为其上覆二叠系含煤地层和第四系砂泥岩,主要热储层为寒武系固山组白云质灰岩;热水的水质类型为HCO3SO4—NaCa,大气降水是热水的主要来源,地下热水的垂直运移是形成热水主要原因。根据注水试验资料评价了断层带的地热资源量,按照地热资源利用率为15%,初步估算了断层带地热资源量为2 491.735万t标准煤,认为采用注采结合的方法开采地热资源是较为合理的。最后建议加强中部地区地热资源的进一步勘查研究,以获得更多的地热资源。

| Abstract: | Through the analysis of Anshang-Xiangjia fault zone geotherm geological characteristics,considered that the fault zone in the study area can be divided into three parts,and the geothermal anomaly is most obvious in the southern part.Caprocks of the geothermal reservoir are overlying Permian coal-bearing strata,Quaternary sand and mud,while the main geothermal reservoir is dolomitic limestone in the Gushan Formation,Cambrian System.The geothermal water quality type is HCO3SO4-NaCa,atmospheric precipitation is the main source,vertical migration of water is the main reason of geothermal water forming.Based on water injection tested data,estimated geothermal resource in the fault zone,according to 15% rate of utilization,preliminary estimated geothermal resource in the fault zone is 24.91735 MT coal equivalent,and considered that to use injection-production method in geothermal resource exploitation is reasonable.Finally,a suggestion to strengthen further exploration and research in the area for more geothermal resource has put forward. |
