承压、封闭性好的井孔-含水层系统可以看作是安装在地表附近的高灵敏度的体应变仪,它能观测到固体潮、地震波、气压效应、降雨负荷、海潮负荷以及断层活动等多种应力应变变化现象。井水固体潮分析结果既反映了液态地核动力学效应造成的日波振幅比随频率的变化,还可确定含水层体积模量、孔隙度、渗透率等参数以及基岩裂隙参数,某些参数随时间的变化可能与构造活动有关。水震波分析结果可以确定井孔-含水层系统的频响特征。故井孔-含水层系统是一个探索地下信息的重要窗口。
Well-confined, well-closed boreholes-aquifer systems can be viewed as highly sensitive body strain gauges mounted near the surface that can detect solid tides, seismic waves, atmospheric effects, rainfall loads, ocean tides, and fault activity A variety of stress and strain changes phenomenon. The analysis results of well water tide reflect not only the change of daily wave amplitude ratio as a function of frequency but also the parameters of bulk modulus, porosity, permeability and bedrock fissure parameters of aquifer, some of which Changes in parameters over time may be related to tectonic activity. The results of the water shock wave analysis can determine the frequency response characteristics of the borehole-aquifer system. Therefore, the wellbore-aquifer system is an important window for exploring underground information.
