基于Hvorslev和CBP模型的微水试验应用

Application of Slug-Water Test Based on Hvorslev and CBP Model

摘要: 结合某工程实例，在低渗透地层开展微水试验，并将试验结果与传统的压水试验结果对比，分析表明微水试验结果较压水试验结果偏大，该方法受温度效应、钻孔储存效应以及皮肤效应影响较大，且所求参数仅能反映钻孔附近有限半径范围内含水层的渗透特性。但由于微水试验法具有试验周期短、成本低、设备简单、分层测试、无污染的特点，在工程勘察中具有良好的运用前景。

Abstract: Combined with a project example, the slug-water test is carried out in the low-permeability stratum, and the test results are compared with the traditional packer permeability test results. The results show that the slug-water test results are larger than the packer permeability test. The method is affected by temperature, pore storage effect and skin effect, and the required parameters can only reflect the permeability of the aquifer in the limited radius near the borehole. However, the slug-water test method has the advantages of short test period, low cost, simple equipment, stratified test and no pollution. It has a good prospect in engineering survey.
