摘　　要：地下流体观测是地震监测预报的一项重要工作。地震地下流体观测井通常为承压单井,需要通过单井试验确定观测含水层的水文地质参数。在湖北省武汉和黄梅地震地下流体观测井分别进行了非稳定流水位恢复试验和微水试验,确定了观测含水层的水文地质参数,取得了较好的效果。鉴于渗透系数K反映了含水岩层的物理状态,建议将其动态变化纳入地震地下流体的监测体系。Observation of underground fluid is important work of seismic monitoring and prediction. Observation well of seismic underground fluid is usually a single borehole in a confined aquifer,so we determine hydrogeological parameters of the observation aquifer just by a single- well pumping test. We applied unsteady flow pumping- recovery test and slug test to two observation wells of seismic underground fluid in Wuhan and Huangmei,Hubei Province,and achieved good results. The hydraulic conductivity K reflects the physical state of the aquifer,so we suggest it to be added to the seismic underground fluid monitoring system.
