摘　　要：对河北省怀来县后郝窑地热田热水井开采的情况进行了调查。并分析了热水井开采对怀4与怀3二口井水位、水温、流量、氡与汞动态的影响,结果证明同层热水井开采对地震地下流体动态的影响是严重的。这种影响在多年、年、月、日等不同频带的各种测项的动态中和模拟与数字化不同观测方式中都有所表现,而且开采结束之后还存在一个多月的影响时间。Exploitation situation of hot water well in Houhaoyao thermal field and the influence of exploitation of hot water well on water level, temperature, radon and mercury's dynamics in Huai 3 and Huai 4 wells are investigated in detail. The results demonstrate that the influence of exploitation of hot water from the same thermal layer on the underground fluid dynamics is serious. Such an influence is expressed in the dynamics of different observational items with different frequency in the time scale of several years, year, month and day, and it still exists more than one month after finishing the exploitation.
