内蒙古自治区地热资源分布特征与潜力评价

Distribution characteristics and potential evaluation of geothermal resources in Inner Mongolia

立足内蒙古地热地质条件,分析了全区地热田分布规律、形成机理,进行全区地热资源量计算、地热资源开发利用模式研究。针对不同地热区和热储类型确定了隆起山地对流型和山前平原、沉积盆地型地热田两种类型的计算方法与参数进行潜力评估。结果表明:内蒙古地热资源总量为1.99×1016k J。实际开采热量4.60×1011KJ/a,可替代的常规能源量2.6×104t/a,可减少CO2气体排放量6.24×104t/a、可减少SO2气体的排放量443.89t/a,可减少氮氧化物(NOx)排放量156.67t/a,可减少悬浮质粉尘208.89t/a,可减少固体废弃物排放量(以每年多少吨煤渣计量)2.62×103t/a。

In this research,geothermal distribution,genesis and development and utilization of geothermal resources in Inner Mongolia were analyzed. Based on the analysis of geothermal field distribution and formation mechanism,the different geothermal fields of different genetic types in this region were studied. The potentials of geothermal fields of uplift mountain convection and piedmont plain,sedimentary basin were assessed. The results show that the total amount of geothermal resources in Inner Mongolia is 1. 99 × 1016 k J. The actual energy consumption is 4. 60 × 1011KJ/a; it can replace the conventional energy of 2. 6 × 10~4t/a,reduce CO_2 emission by 6.24 × 10~4t/a,reduce the SO2 emission by 443. 89t/a,reduce nitrogen oxides（NOx） emissions by 156. 67t/a,reduce the suspended dust by 208. 89t/a,and reduce solid waste emissions（measured in the number of tons per year cinder） by 2. 62 × 103t/a.
