鲁29井井口变压试验

EXPERIMENT ON PRESSURE VARIATION IN WELL AIR IN LU-29WELL

  • 摘要: 本文介绍了鲁29井井口变压试验结果。试验结果表明,井水位对井口空气压力变化的响应与变化周期有关。井口空气压力变化的周期越大,则井水位的响应幅度越大,而响应的位相滞后越小。对于长周期压力变化的响应,在量值上为井口压力每hPa变化引起水位10.2mm的变化。由于水在井孔与含水层之间的渗流造成了井水位对空气压力变化的响应产生位相滞后。这些试验结果与实际观测资料分析的结果及理论模型研究的结果是一致的。

     

    Abstract: In this paper the experiment results of pressure variation in well air in Lu——29 well have been introduced. The results show that the response of well water level to pressure variation in well air has relation to the period of pressure variation. The greater the period of pressure variation in well air is, the greater is the response amplitude of well water level, while the smaller is the phase lag of the response. The response quantity of well water level to pressure variation of the long period is 10.2mm in well water level variation caused by pressure variation of per hPa in well air. The phase lag produced by the response of the well water level to variation of air pressure results from permeation of water between the well and aquifer.#br#These experiment results correspond with the analysis results of the observed data and research of theoretical model.
