深井注水或抽水诱发地震,世界上已有先例。我国任丘高产油田,自1976年开发以来,随着注水量剧增,小震活动逐渐向油田集中与增强,如从1975～77年间,共发生4次 M_L>1的地震,而1978与1979年的地震次数较前分别增加4.3倍与9.5倍,地震波能量释放较前分别增加34.6倍与901倍。诱发地震的骤然爆发引起了国家有关部门的关注。国家地震局地球物理研究所积极协助油田部门于1980年开始组建我国第一个深井地震传输台网和培训观测人员,年底前两个台已开始试验记录。深井液面前兆监视网也相应在建设
Deep-well water injection or pumping-induced earthquakes have precedents in the world. Since its development in 1976, Renqiu High-yielding oilfield in our country, with the increase of water injection, the activity of small earthquakes gradually concentrates and strengthens to the oilfield. For example, from 1975 to 1977, there occurred a total of four earthquakes with M_L> 1, while in 1978 and 1979 The number of earthquakes in 2006 increased by 4.3 times and 9.5 times respectively, and the energy release of seismic waves increased by 34.6 times and 901 times respectively. The sudden explosion triggered the earthquake caused the concern of the relevant state departments. The Institute of Geophysics of the State Seismological Bureau actively assisted the oilfield department in starting the formation of the first deep seismic transmission network and training observers in China by 1980, and the two stations before the end of the year have begun to test the records. Deep well precursor monitoring network is also under construction
