摘　　要：卜南堡地热田内地热资源丰富,但区内缺少对地热资源量的科学性评价,导致区内地热资源开发利用程度较低。通过分析区内地热地质条件,初步圈定了资源量范围,并利用热储法对雾迷山组热储层的地热资源量、可开采量进行了计算。卜南堡地热田地热资源量为8.422×10^(17)J,折合标准煤2.874×10^(7)t,地热水储存量为374.300×10^(6)m^(3);100 a内可开采地热资源量为4.211×10^(16)J,折合标准煤1.437×10^(6)t,地热水可开采量为281.716×10^(6)m^(3),属于中型低温热田。区内地热水不能作为生活饮用水、农田灌溉水和渔业用水,适宜作为理疗用水、供暖和天然矿泉水使用。The geothermal resources in the Bunanpu geothermal field are abundant,but there is a lack of scientific evaluation of the amount of geothermal resources in the area,resulting in a low degree of development and utilization of geothermal resources in the area.By analyzing the geothermal geological conditions in the area,the range of resources is preliminarily delineated,and the geothermal resources and exploitable amount of the thermal reservoir of Wumishan Formation are calculated by using the thermal storage method.The geothermal resources in the Nanpu geothermal field are 8.422×10^(17)J,equivalent to 2.874×10^(7)t of standard coal,and the geothermal water storage is 374.300×10^(6)m^(3).The recoverable geothermal resources within 100 years are 4.211×10^(16)J,equivalent to 1.437×10^(6)t of standard coal,and the recoverable geothermal water is 281.716×10^(6)m^(3);,which belongs to the medium-sized low-temperature geothermal field.The geothermal water in the area cannot be used as drinking water,farmland irrigation water and fishery water.It is suitable for use as physiotherapy water,heating and natural mineral water.
