摘要
高七井静水位自2018年3月27日开始出现破年变转折下降变化,并于2018年6月22日开始出现恢复变化,期间水位最大下降幅达1.65 m。针对高七井静水位此次出现的异常变化,在排除外界干扰的基础上,综合数据对比分析结果、历史震例分析结果、地震活动性分析结果、水位校测实验结果以及不同仪器水位对比观测分析结果等,显示高七井对远场映震效能较好,此次出现的异常变化真实可靠,与2018年5月28日吉林松原发生的5.7级地震有一定的成因联系,为区域构造应力调整作用引起。
Water level in Gaoqi Well were turned decrease on March 27th 2018,and return to normal on June 22th 2018.The max amplitude was about 1.65 meters.For the abnormal variation in Gaoqi Well of this time,on the basis of the exclusion the interference,the results for the data contrast,reflecting earthquake ability,seismic activities analysis,water level calibration experiment and comparison observation experiment for water level of Gaoqi well were analyzed.The results show that the well of Gaoqi well had a better earthquake-reflecting ability for field precursors,and the change of water level were reliable,and had a close relationship with the Songyuan Ms5.7 earthquake in Jilin on May 28th 2018,which the stress adjustment in this area is the main reason to cause the water decline.
