盘一井气氡脱气装置改造实验研究

Transformation Experiment of Gas Radon Degassing Device in No.1 Well of Panjin

为了改进盘一井气氡的自动脱气效果,去除干扰,提高观测资料质量,2015年11月3日盘锦地震台对气氡脱气装置进行改造实验。通过应用中国地震局流体学科组许秋龙研制的气氡脱气装置替换掉原来的脱气装置,截至2016年9月已取得近10个月的观测数据。分析了观测过程中遇到的问题并进行了相应的改进,改进后观测数据不再受气温、气压的干扰,流量干扰与漏气问题也得到了一定的控制。

In order to improve the automatic degassing effect of radon gas in the first well, remove the interference and improve the quality of observation data. Reconstruction of radon degassing device in Panjin seismic station in November 3, 2015. The gas degassing device, which was developed by Xu Qiulong, a fluid group of China Earthquake Administration, replaces the original degassing device, which has been observed for nearly 10 months. The problems encountered in the observation process are analyzed. After improvement, the observation data is no longer affected by the air temperature and air pressure, and the flow interference and leakage problem are also controlled.
