摘要:
采用piper图、主要离子相关等方法对安徽霍山33井2021—2023年井水13次水样离子检测结果进行分析,结果显示:该井地下水化学类型为HCO3-SO4-Ca-Mg型水,水中离子以HCO3-、Ca2+、Mg2+为主,由于井水属于承压水,埋藏深度大,径流补给途径长,溶解—溶滤作用强烈,从而引起离子浓度高于地表水;氢氧同位素的结果显示,该井主要受到大气降雨补给;离子浓度时间序列显示,在2022年10月10日霍山3.0级地震前后,2022年7—8月的离子检测中,出现Ca2+、Mg2+浓度升高,SO42-和Cl-浓度降低的变化,地震后恢复到正常背景值,该变化可能反应了地震孕育过程有关。
Abstract:
The ion detection results of 13 water samples from the Huoshan Well 33 in Anhui Province from 2021 to 2023 were analyzed by using the piper plot and main ion correlation methods. The results show that the chemical type of groundwater in this well is HCO3-SO4-Ca-Mg type water,and the main ions in the water are HCO3?,Ca2+, and Mg2+. As the well water is confined water, with a large burial depth, long run off supply path, and strong dissolution and filtration,the ion concentration of the well water is higher than that of surface water. The hydrogen and oxygen isotope results indicate that the well water is mainly recharged by atmospheric rainfall. The ion concentration time series shows that before and after the Huoshan M3.0 earthquake on October 10th, 2022, the Ca2+and Mg2+ concentrations increased, and the SO42?and Cl?concentrations decreased during the ion detection from July to August,2022. After the earthquake,they returned to normal background values,which may reflect the earthquake preparation process.
