本文对深井记录地震波的特征和机理进行了分析研究,指出利用井水位记震能力随时间的变化及井水地震图图象特征,对预报邻近地区的中强地震和研究断层活动性有一定意义。深井水位对地震波的响应能力,主要取决于井孔——含水层系统的固有周期、自身的频带宽度以及水位记录仪的频率响应,前者是衡量地震观测井灵敏程度的主要标志之一。
This paper analyzes and studies the characteristics and mechanism of seismic waves recorded by deep wells. It is pointed out that the change of seismic potential of well water level with the time and the image features of well-water seismograms have some significance for forecasting moderate-strong earthquakes in the adjacent area and studying the fault activity . The response of deep well water level to seismic wave mainly depends on the inherent period of borehole-aquifer system, its own frequency bandwidth and the frequency response of water level recorder. The former is one of the main indicators to measure the sensitivity of seismic observation wells.
