| 摘 要： | 基于应力敏感性渗流特征,针对承压含水层完全井,建立了带有渗透率应力敏感性系数的渗流数学模型。计算结果表明随着应力敏感性系数系数的增大,水位降深-流量关系曲线逐渐偏离线性关系,应力敏感性系数越大,在相同的水位降深条件下,出水量越小;同时,随着应力敏感性系数的增大,水头损失幅度也增大,任一流量下,应力敏感性系数越大,靠近井底附近位置处的水头损失幅度也越大。

| Abstract: | Based on characteristics of stress sensitivity,mathematical model of flow through porous media for fully penetrating well in confined aquifer of stress sensitivity was established.The calculation results show a deviation from linear relationship for drawdown-discharge relationship curve.The discharge decreased with increasing of deformation coefficient under the same drawdown.The drawdown increased with increasing of deformation coefficient under any discharge. |
