摘　　要：含水层皆具有异质性,因而垂向上不同深度的渗透系数会有差异,为了准确的获得含水层不同深度的渗透系数,采用多深度微水试验实现按需分层推估渗透系数的目的。利用前人建立的微水试验分析模型,对实际测得的一组多深度微水试验数据进行分析,推估出试验区内井N01周边不同深度的渗透系数值,确定了渗透系数的垂向变化,并验证了其与地质钻探岩性资料基本一致。Due to aquifer heterogeneity,the hydraulic conductivity at different depth of the aquifer is different.The multilevel slug test is an efficient and practical single-well hydraulic test to determine the vertical distribution of hydraulic conductivity near the test well. The existed slug test models are used here to analyze one group of multilevel slug test field data,and to estimate the hydraulic conductivity at different depths near the test well N01. The vertical distribution of hydraulic conductivity is determined and the values of the hydraulic conductivity are verified to be consistent with the geological drilling data.
