新疆新25号泉H_(2)S自动观测技术方案及试验应用

Introduction of the Automatic Observation Method of H_(2)S Gas in Hot Spring Water in Xinjiang

为探索H_(2)S自动化观测的实现途径,制定了H_(2)S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H_(2)S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 H_(2)S 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 H_(2)S automatic observation.This paper introduces the technical scheme of using industrial combustible gas H_(2)S alarm detector and carries out a H_(2)S observational test in No.25 Spring of Xinjiang.The results show that it is feasible to use this alarm equipment instead of manual H_(2)S 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 H_(2)S.
