中低温热储及其井中热场

中低温地下热水有着广阔的开发利用前景,其成因及赋存规律的研究,是合理勘探、开发的基础。本文从地层、构造及水文地质条件入手,根据地热传导原理,研究了传导型热储的发育条件,划分了主要热储类型。在此基础上,对井(孔)中热场及井液温度变化规律进行了分析,给出了井液温度分布曲线及井液温度变化与地层的对应关系。该成果对勘探开发地下热水有指导意义。 

LOW-TO MID-TEMPERATURE THERMAL STORAGE AND THERMAL FIELD IN HOLES

The groundwater with low to mid temperature has great potential for development and usage.The research on its origin and occurrence is the foundation for rational exploitation and development.In the light of stratigraphic and hydrogeologic conditions,the development conditions conductive thermal storage are studied as well as the primary types of thermal storage are divided,based on the principles of geothermal conducrion.The variation regularities of thermal field and the temperature of drilling fluid are analyzed,providing the temperature distribution curves of drilling fluid and corresponding correlation between temperature and strata.The result is available for guiding the thermal groundwater development.
