针对2011年芜湖皖28井水位破年变异常，系统梳理该井相关资料，利用水位变幅、相关性分析及相对变差率进行分析，结果表明，该项异常信度较高，反映区域构造活动信息，是周边几次中等强度地震的共同前兆。通过剩余曲线、从属函数等数学方法，对该井历年水位观测数据进行异常识别，研究表明，该井水位异常主要表现为短期异常特征，与该井孔西北、西南侧中等地震有较好的对应关系。

This article according to the Wuhu 28^th well broken abnormally in 2011 inAnhui province，and the system sorts out the relevant information well，then take advantage of  level luffing and correlation analysis and the relative variation rates to analyze it. The results show that the abnormal higher reliability，which reflects the regional tectonic activity information，Simultaneously，which is a common precursor to its surrounding several moderate earthquakes. Subsequently，Through mathematical residue curve and subordinate function to recognize abnormities for the well over the water level observation data. Research shows that the water level anomalies mainly for short term anomaly and the surrounding the borehole medium earthquake good corresponding relationship in the northwest and southwest side.
