【摘要】 基岩山区地热形成必须具备"储、盖、通、源、滞"五大基本要素,以湖南株洲湾塘地区地热成因为例,说明怎样利用地热勘查手段来分析论证株洲湾塘地区地热形成的五大要素,建立热储概念模型,确定地热井位置。为提高地热钻探成井率,在基岩山区钻探施工时,建议使用气举反循环清水钻进工艺。更多还原

【Abstract】 The formation of geothermal resources in basic rock mountain areas should have five basic elements,such as reserve,cover,tunnel,source and block.Taking geothermal origin in Wantang area of Zhuzhou city in Hunan province as an example,how to analyze the above five elements by means of geothermal exploration in this area have been introduced.Thus,a reservoir conceptual model can be set up,and the location of geothermal wells can be determined.In order to increase success rate of the geothermal wells,it is recommended air-lift reverse circulation drilling technology of clear water during drilling construction can be used in basic rock mountainous areas.更多还原
