摘要
利用基于流量的相似方法分析了井流场中的渗透情况 ,此方法以流量作为未知函数 ,不仅避开了井口奇点问题 ,而且还可根据实际情况方便地推导出降落漏斗的影响区域半径 (影响半径 R)。此方法可适用于完整井、不完整井的定流量或不定流量抽(注 )
In this paper, the seepage in unsteady well flow domain is analysed by the similarity method, in which the discharge is taken as an unknown function. This method is also applicable to the problems of pumping (watering) at constant or inconstant rate in fully penetrating well or partially penetrating well. Then not only the problem of queer dot at the well bore is avoided, but also the radius of influence domain (R) of the depression cone is convenient to deduce.
