ANALYSIS OF THE WATER TEMPERATURE ANOMALY IN NO. 4 WELL AT WENJIN STREET IN HENGSHUI CITY
-
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。Abstract: 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.
