Abstract

Abstract

To find out a suitable equation for single-well pumping test in double-porosity aquifer, it takes wellbore storage effect into consideration and present the double-porosity non-Darian model with wellbore storage effect based on double-porosity non-Darcian model in this study. Taking a single-well pumping test as an example, the results show that the simulation curve has the highest accuracy when using the double-porosity non-Darcian model proposed in this study; taking non-Dacian effect into consideration is more suitable when the pumping rate is relatively large and the flow in aquifer shows non-Darcian property. When considering non-Darcian effect, we can have a better inversion of the instantaneous drawdown in early time; when regarding the aquifer as double-porosity, we can portray the weak to strong process of the water exchange in fracture and porosity media. In that case, the double-porosity non-Darcian model with wellbore storage effect presented in this study is suitable for single-well pumping test in double-porosity aquifer.
