INFLUENCE OF WATER EXPLOITATION FROM MA 17^TH WELL TO THE WATER LEVEL OF MA 16^TH WELL

In order to test the environmental influence of water level observation to some deep wells in Hebei plain area, we compared the water level of Ma 17^th earthquake observing well and Ma 16^th geothermal exploita-tion well to find out the influence of water exploitation in Ma 16^th Well to Ma 17^th Well.The results show that the annual variation of water level in Ma 17^th Well is not caused by the water exploitation in Ma 16^th Well, but by air pressure interference.
