关于一种潜水井裸井slug数学模型的探讨及实证

利用slug试验测量渗透系数在国内外已有了比较成熟的发展,但是专门应用于潜水井裸井的slug数学模型却极少出现在各类文献中。通过注水高度对潜水含水层厚度的影响推导对潜水含水层完整井的slug数学模型,此模型与传统的Bouwer and Rice模型相比考虑了注水后潜水面水位的增加对渗透系数K的影响,并结合室内变水头渗透试验和前期抽水试验来验证在工程实例运用此模型算出的渗透系数的准确性。更多还原

Discussion and Verification of a Slug Mathematical Model for Naked Well in Submerged Aquifer

Using slug test to get the permeability coefficient of aquifer has a relatively mature development,but the slug mathematical models specially applied to the snaked well in submerged aquifer rarely appear in literatures.So,the slug mathematical model for the naked well in submerged aquifer is deduced by considering the effect of the increased thickness of submerged aquifer.Compared with Bouwer and Rice model,it considers the effect of the elevation of the submerged aquifer’s water level after water-injecting into the well upon the permeability coefficient K.Combined with the variable head permeability experiment and pre-pumping test,the accuracy of the permeability coefficient calculated by this model in engineering examples is verified.
