| 摘 要： | 本文从气压影响承压井水位的偏微分方程出发,考虑到井孔和含水层之间相互渗流的边界条件,得出了方程的解。给出了承压井水位对气庄动态过程响应的气压效率和位相滞后。讨论了气压效率和位相滞后与水井含水层系统各参数的关系。并指出气压效率越大的承压井,其含水层对应力应变的敏感程度越差。

| Abstract: | Starting from the partial differential equation of the effect of barometric pressure on the water level of a confined aquifer, and taking into consideration of the boundary conditions between well and aquifer, we have obtained the solution of the equation and presented the barometric efficiency and phase lag of the response of the water level of the confined wells to dynamic process of barometric pressure. The relationship between this barometric efficiency and phase lag and the other parameters of well-aquifer system are discussed. It is pointed out that wells with bigger barometric efficiency are poorer in the sensitivity of aquifer towards stress and strain. |
