摘要
分别从实验分析(温度梯度分析及井下电视探查)、化学分析(水质及水化学组分、同位素分析)和物理分析(滞后时间与阶跃响应函数分析、频谱分析、水位潮汐参数计算分析)等方面,对海原红羊井水位、水温自2015年5月以来,多次出现的瞬时同步变化现象进行了分析论证。结果显示引起这一现象的原因可能与井下51m处井壁受腐蚀破裂,使得破裂处含水层的地下水与井筒内井水快速交换所致,并非地震构造活动引起的前兆异常。
From the experimental analysis(temperature gradient analysis and downhole TV exploration),chemical analysis(water quality,water chemical composition and isotope analysis)and physical analysis(lag time and step response function,spectrum analysis,calculation and analysis of water level and tidal parameters)and other aspects,the instantaneous and simultaneous changes of water level and temperature in Haiyuan Hongyang well since May 2015 were analyzed.The results show that the cause of this phenomenon may be due to the corrosion and rupture of the shaft wall under 51m in the well,which caused the rapid exchange of groundwater in the aquifer and the well water in the wellbore,not a precursor anomaly caused by seismic tectonic activity.
