摘　　要：通过对麻林桥地区地热勘查、钻探及物化探资料的深入分析,查明了该地区地质构造特征、地温场分布特征以及地下水化学组分特征,该区断裂带岩体破碎,是较好的储热、导热构造,地温场平面分布方向与断裂走向一致,zk1,zk2,zk4孔井温测井曲线反应了地温场垂向变化规律,地下热水垂向温度的变化与裂隙的发育程度有很大联系,对比分析浅层地下水与地下热水水样检测数据,浅层地下水与地下热水存在水力联系,综合分析后建立地热形成模型,为今后该地区地热资源的合理开发利用以及科学的管理提供理论依据.Through the in-depth analysis of the material of geothermal prospecting, drilling and physical ＆ chemical exploration in Malinqiao, characteristics of this region, such as geological structure, geothermal field distribution and chemical composition of underground water are identified. The broken rock mass makes it a good structure for heat storage and conduction. Planar distribution of ground temperature field direction is consistent with the strike of the fault. The hole temperature log curves zkl, zk2 and zk4 reflect the change rule of vertical ground temperature field. The change of vertical underground hot water temperature is closely related to fracture development degree. Compared with the water sample test data of shallow groundwater and geothermal water, this paper finds that the two are relative in the aspect of water power. After the comprehensive analysis, this paper builds the model of the earth heat forming system, which lays a theoretical foundation for the reasonable exploitation and scientific management of geothermal resources in this area.
