通过对地质、钻探资料和物探测井、岩土体热物性参数测试等资料的研究，结合综合勘查技术方法和对已有资料的二次开发，查明了天津地区浅层地热能赋存条件，尤其是岩土体的热物理参数变化规律，并借助Excel办公软件，采用数理统计方法对岩土体热物性参数的变化进行了分析。结果表明区内岩土体的热导率为1.23～1.62 W/(m·℃)，比热容为1898.52～2201.70 J/（kg·K）；粘土和粉质粘土含水量在19％左右时热导率最佳，粉土和粉砂含水量在17％左右时热导率最佳。该区浅层地热能赋存丰富，具有很广阔的开发前景。

Based on the information of the integrated drilling, exploration wells, thermal properties of soil and rock testing data and comprehensive exploration methods with the second development of the present data, we identifyed the occurrence of the shallow geothermal conditions, particularly the rock and soil variation of thermal physical parameters. And we analysed the thermal properties of soil and rock by the mathematical statistics meth-od. The results show that the thermal conductivity of the soil is 1.23~1.62 W/( m·℃), the specific heat capaci-ty is 1898.52~2201.70 J/( kg·K ).When the clay and silty clay has a moisture content of about 19%, the ther-mal conductivity is best, and silt and silty sand has a moisture content of about 17%, the thermal conductivity is best. Tianjin is rich in shallow geothermal energy with wide development perspective.
