Abstract:: The gas-gathering and degassing device is one of the important key technologies in the continuous observation system of the seismic underground fluid.The efficiency and stability of the degassing and gass gathering equipment directly affects the quality of observation data.According to the type of underground fluid observation wells(springs),water temperature,salinity,water flow and other characteristics,5 kinds of gas-gathering and degassing devices,including the device with large flow and low salinity,the device with small flow and low salinity,the device with large flow and high salinity,the device with small flow and high salinity,the vacuum degassing device,and the static water well degassing device,have been developed.These devices also have been tested and applied in Chengxian station in Gansu province,Haiziquan spring in Sichuan province,Lujiang station in Anhui province,Wushan station in Gansu province,Xiaguan station and Mangbang station in Yunnan province.So far these devices have basically helped to solve the problems of clogging,low degassing rate,and unstable degassing in the old underground fluid observation system.
