| 通过对武蛟地热田已有钻孔及区域地热地质资料,结合前人勘查资料,分析了武蛟乡地热田区域地质特征、地温场分布特征、地热水水化学特征及补径排条件,说明武蛟地热属深循环途中正常大气热流加热火山型地热系统,地热成因模式为断裂岩溶复合型,地热田的热储模型为断裂对流型带状热储。采用热储法计算出研究区内控制级的允许放热量为6.40×105KcaL·h-1,推断级的允许放热量为9.08×105KcaL·h-1；研究区内年可开采水量为63.02×104 m3。初步摸清武蛟地热田分布规律及资源量,为武蛟地热田地热资源的合理开发利用提供科学依据。 |

| Based on available drilling data of the Wujiao geothermal field and regional geothermal geological data in combination with results of recent exploration projects,the authors analyzed the regional geological feature,geo-temperature field,hydrochemical characteristics,recharge and runoff discharge conditions of Wujiao geothermal field.The investigation indicates that Wujiao geothermal field geothermal system is a volcanic geothermal system with normal atmospheric heat flow during deep circulation.The geothermal genesis model is fault-karst complex type,and the geothermal field is dominated by fracture convective banded thermal reservoir.calculated by thermal reservoir method,the allowable heat release by the control management level in the study area is 6.40×105KcaL/h,the inferential level is 9.08×105KcaL/h.The annual recoverable water reserve is 63.02×104 m3.The distribution regularity and resource quantity of the Wujiao geothermal field have been ascertained,which provides a scientific basis for the rational development and utilization of geothermal resources in the Wujiao geothermal field. |
