摘　　要：衡水市问津街４号井１９９１年９月出现水温大幅度异常，经水质分析、井孔普查方法初步证明，水温大幅度升高与地震无关。进而通过水温热异常扩散范围调查、现场实验观测以及井下提水设备解剖，查清了水温升高的真正原因。该异常的剖析落实，稳定了生产生活秩序，产生良好社会效益，并对今后落实分析该类异常具有参考价值。The No. 4 well at Wenjin Street in Hengshui City showed a large amplitude anomaly of water temperature in September 1991. By water quality analysis and the general investigation of the well, it. is preliminarily proved that the large amplitude increase of the water temperature had no relation with earthquake. Then, by investigation on the range of scatter of thermal anomaly of water temperature, in-situ experimental observation and analyzing the downhole water-extracting equipment, the real reason for the water temperature increase has been found out. The thorough investigation of the anomaly has stabilized the production and living orders, and produced a good social result.
