During a long time in the past, the treatment of well point has been a difficulty in academia. However well pumping is still inevitable in civil engineering circles due to its effective role on groundwater control. Firstly, the currently available treatment methods of well point are summarized. Through comparison between these existing methods and theoretical analysis, a drainage substructure is advanced, of which the inner layer is a square having equal perimeter with the actual well pipe. Results of numerical simulation upon a field pumping test prove the effectiveness and feasibility of proposed drainage substructure method, which may contribute to the well point simplification in future research.

In this paper, we presented results of interpretation of Self-Potential (SP) signals produced by pumping test experiment of heterogeneous aquifer. Heterogeneity is represented by zone with low and high hydraulic conductivity in two types of configuration: planned boundary and strip-layer. We studied five models for each type of heterogeneity with two variants of hydraulic conductivity. We carried out three-dimensional modelling with the use of Modflow (for hydraulic heads and electrical potentials) and ElSources (for current source term). We obtained SP distributions Self-Potential produced by pumping test which indicate heterogeneity. We calculated the values of the anomalous field for a detailed study of the heterogeneties. We found a correlation between SP and drawdown for the case of heterogeneity with low hydraulic conductivity. We defined the both boundaries of the strip clearly for zone with low hydraulic conductivity. The outer boundary of the strip-layer was not fixed due to the high hydraulic conductivity of the heterogeneity and low hydraulic gradient at the boundary. We estimated dependence of horizontal thickness of heterogeneity on SP distribution. The results can serve as a base for defining the heterogeneties in the aquifer.
