摘　　要：综合贵州省地热研究相关成果资料,分析贵州省地热流体资源赋存条件及地热水资源分布特征,以此为基础将贵州省划分为110个地热资源量估算区,参照省内地热流体资源主要集中在断裂带周边的实际特点,采用设计布井法、泉(井)流量统计法和比拟法对贵州地热流体可开采资源量进行估算。结果表明:贵州地热流体资源的形成和分布,受省内地质构造特点及其在全国构造所处部位的控制,地热资源成因类型可划分为沉积盆地传导型地热储和隆起山地断裂对流型地热储,总体热储温度一般小于90℃,为低温地热资源;估算出贵州省地热流体可开采资源总量为23190.37 m^(3)/a,其中设计布井法估算的资源量为15926.22 m^(3)/a,天然温泉可开采资源量1183.34 m^(3)/a,地热井可开采资源量6080.80 m^(3)/a,总热能906933.97 Kw,年开采累计可利用热能量476.68×10^(8)MJ。所估算的地热流体可采资源量可为贵州省地热资源的勘查开发规划提供参考依据。Synthesising the information on the results of geothermal research in Guizhou Province,analyzing the conditions of geothermal fluid resources and the distribution characteristics of geothermal water resources in Guizhou Province,based on this,Guizhou Province was divided into 110 geothermal resource estimation zones.Referring to the actual characteristics that geothermal fluid resources in the province are mainly concentrated around the fracture zones,the geothermal recoverable resources in Guizhou were estimated by using the method of designing wells,the statistical method of springs(wells)flow rate,and the method of comparing and contrasting.The results show:The formation and distribution of geothermal fluid resources in Guizhou are controlled by the geological and tectonic characteristics of the province and its location in the national tectonic structure,and the genesis of geothermal resources can be divided into sedimentary basin conduction-type geothermal reservoirs and uplifted mountain rupture convection-type geothermal reservoirs,and the overall temperature of the thermal reservoirs is generally less than 90℃,which is a low-temperature geothermal resources;The total extractable resources of geothermal fluids in Guizhou Province were estimated to be 23190.37 m^(3)/a,among them,the resource volume estimated by the design well distribution method is 15926.22 m^(3)/a,the recoverable resource volume of natural hot springs is 1183.34 m^(3)/a,and the recoverable resource volume of geothermal wells is 6080.80 m^(3)/a,with a total thermal energy of 906933.97 kw,and the cumulative utilisable thermal energy of the annual mining is 476.68×10^(8)MJ.The estimated recoverable resources of geothermal fluids can provide a reference basis for the exploration and development planning of geothermal resources in Guizhou Province.
