| 摘 要： | 分析1993年以来荣昌及周边地区地震活动与深井注水的关系。对2008年以前注水井位置、注水量与地震活动进行对比，对2008年以后地震进行重新定位，统计地震空间分布，探寻其与深井注水的关系，并对注水量与地震频度进行相关分析。研究认为，深井注水初期对地震活动影响较大，之后有所减小，可见地震活动主要受地质构造控制。

| Abstract: | In this article,the relationship between seismic activity and injection since 1993 is studied for Rongchang and its surrounding area.Location of injection wells and water injection quantity are contrasted with activity of earthquakes before 2008.Spatial distribution images of earthquakes are obtained by earthquakes repositioning after 2008.In addition,correlation between injection and frequency is studied.The result is,water injection in deep wells have greater impact on seismic activity in the early of water injection.Then,the impact becomes smaller,and the activity of earthquakes is controlled mainly by the structure. |
