摘　　要：对比分析了唐山地区同一地质单元内、同一观测含水层、水位动态相同的山西水 2井和岳 4 2井记录的水震波曲线 ,显示两井记震能力相差很大 .从井孔结构、地震面波特性等方面分析了两井记震能力差异性的成因机理 .结果表明 ,井孔的固有周期是影响水位记震能力大小的首要条件 .The curves of recorded seismic wave on groundwater level in Shanxi water 2 and Yue 42 wells,in Tangshan city,Hebei province,are contrasted.Both wells locate in the same geological unit and same water bearing bed,with same water level dynamic style,but have very different abilities of recording seismic wave.The mechanism of the difference in two wells is analysed from the structure of wells and the property of seismic surface wave.The result shows that the inherent period of well hole is the first important condition for influencing the ability of recording seismic wave of groundwater level in well.
