井水位对气压扰动的响应

Response of Water Level on the Well to Air Pressure Perturbation

分析了河北省地震地下流体井网的黄骅、深州、无极、宁晋、永年五口深井水位对气压扰动的响应。结果表明,气压瞬间的大幅度变化能够引起水位的准同步变化,由此求得的井水位气压系数与利用日均值序列计算的气压系数基本相当;与日均值序列相关分析结果比较,水位对气压扰动的响应表现出了一定的波动性。

The paper analyses deep well＇s water level responding to atmospheric pressure perturbation disturbance,the wells are involved underground fluid well net of earthquake in Hebei Province such as Huanghua well,Shenzhou well,Wuji well,Ningjin well,Yongnian well.The result shows that atmospheric pressure momentary change on a large scale can cause the accurate synchronism change of water level,atmospheric pressure coefficient of water level calculated by this method is consistent to the result calculated by daily equal sequence.Compared to the correlative analysis result of daily equal sequence,water level responding to atmospheric pressure disturbance represents certain volatility.
