| 摘 要： | 王4井因受井区地热开发的影响,于2008年12月断流停测。2010年对原观测井口装置进行改造,开始进行抽水观测水汞试验研究。在新的观测方式下,为确保观测数据稳定、可靠,本文从抽水观测的观测条件方面,对不同取样位置和抽水时间对水汞测值的影响进行了试验。试验结果表明,不同抽水时间和不同取样位置抽水观测对水汞测值影响不大,这一结论与水汞本身的化学特性相一致。认为在没有自流井的地区,只要选择灵敏的观测点使用抽水方式采样,固定观测条件,依然可以进行水汞监测。

| Abstract: | Because of the extraction of geothermal resources,Wang-4 well has dried-up and stopped observing in December 2008.In order to pump water and study the observation of water mercury,the equipments modification of the observation well had been done in 2010.To ensure the new observation data is stable and reliable,the pumping tests have been conducted to research the influence of pumping conditions and pumping time.The results show that the pumping time and the pumping position have little effect on measured values of water mercury,and this is consistent with the chemical properties of water mercury.Consequently,this paper proposed that we still can choose sensitive observation sites for water mercury measurements monitoring in the region without artesian well in certain observation conditions. |
