摘　　要：地震地下流体数字化观测中脱气装置的合理设计和选取直接关系到气氡、气汞等逸出气观测项目的数据质量。庐江台现有卧式脱气装置是根据汤池1号井特征自行设计制作,为气氡、气汞等观测项目提供稳定的气源,上述项目投入至今观测数据较为稳定,但相关震例较少。本课题开展了系列实验,对卧式脱气装置的脱气效能做出评估,提出改进建议,并尝试利用新型自鼓泡式脱气装置在汤池1号井开展地下流体监测。The rational design and selection of degassing devices in the digital observation of seismic underground fluids are directly related to the data quality of gas radon,gas mercury and other outgassing observation projects.The existing horizontal degasser at Lujiangtai is designed and manufactured according to the characteristics of Tangchi No.1 well,and provides a stable gas source for observation projects such as gas radon and gas mercury..This subject carried out a series of experiments to evaluate the degassing efficiency of the horizontal degassing device,put forward suggestions for improvement,and tried to use the new self-bubbling degassing device to carry out underground fluid monitoring in the Tangchi No.1 well.
