摘　　要：1998年 3～ 4月 ,西影井水位出现了一次剧烈的下降变化过程。经反复调查落实 ,这是由于西影井附近地区另一口热水井抽水引起的 ,6月 9日做了抽水试验后验证了这一看法。这项工作为研究临近井抽水对地震地下水动态观测井的水位动态影响提供了实例 ,对区分深井地下水前兆异常与抽水干扰有一定的参考意义 ,对热水井布设间距和开发利用有参考价值。A sharp drop appeared in a deep well water level in Xi′an Film Studio from March to April 1998. Through the repeated research, it is discovered that it was caused by pumping water from another deep well near the well in the Xi′an Film Studio, and the pumping water experiments in that well verifies the hypothesis. It provides us an observational case in situ for the inference of pumping water to observational water level, and is also useful to judge which is the precursory anomaly and pumping water influence in deep well water observation. It is also useful to exploit and use the deep well with hot water.
