Much interference has been found in seismic subsurface fluid behaviors. The interference of subsurface water resource exploitation is very universal, and that of hot water exploitation is severe. It affects the observation on subsurface fluid. So, the influence of ground water exploitation on subsurface fluid behaviors should be observed, investigated and researched. Based on hydro-geological settings, exploitation history and actualities of the Jingbei geothermal field, the influences of hot water production on subsurface fluid behaviors in observation wells, which have different hydro-geological settings and different intervals from exploitation wells, are analyzed. Discrepancies of the influence on different observation items are also discussed. Our result shows that disturbance distance of hot water exploitation on subsurface fluid behaviors is within 5km in the Jingbei geothermal field, and the influence on behaviors of the observation wells nearby the water-transmitting fault is most notable. As for the effects on observation items, those on water level and temperature rank first, the escape gas (Rn, Hg) comes second, and that on soil gas (CO_ 2) is inconspicuous.
