备注

为探索H2S自动化观测的实现途径,制定了H2S自动观测技术方案,对漂浮式脱气-集气装置及试验设备进行了改进,将该方案应用于新疆新25号泉进行试验。结果表明:使用这种报警检测设备代替人工H2S测试是可行的,设置脱气-集气装置、采取适当技术措施避免气路堵塞是获取连续稳定观测数据的关键。
The H2S observation in the hot spring water plays an important role in short-term and imminent earthquake prediction as one of the effective underground fluid monitoring items in Xinjiang.However,the traditional manual sampling and laboratory testing methods cannot meet the need of seismic observation.Therefore,it is necessary to explore the possibility and realization of H2S automatic observation.This paper introduces the technical scheme of using industrial combustible gas H2S alarm detector and carries out a H2S observational test in No.25 Spring of Xinjiang.The results show that it is feasible to use this alarm equipment instead of manual H2S test,but the key to obtaining continuous and stable observation data is to set up degassing-gas gathering device and take appropriate technical measures to avoid gas path blockage.The presentation in this paper helps to accumulate experience for the technical upgrading of the observation of the underground fluid H2S.
