Application of numerical modelling for evaluation of operating conditions of water intakes for domestic and drinking purposes in the area of oil fields operation

[摘要] The research is focused on preserving the resources of domestic and drinking water supply in the areas of operation of numerous oil fields. The basis of the study is the well-known principle of protection of groundwater from contamination during its operation, which is implemented at existing water intakes for domestic and drinking water supply through the organization of sanitary protection zones (SPZs). In the conditions of mass application, in order to calculate their boundaries for the most common analytical methods of calculation, in practice, a simplified schematization of hydrogeological conditions is often allowed, not fully considering the complex spatial structure of the filtration flows. The solution of the predicted hydrodynamic problem in the form of a spatial distribution of heads under the influence of water intake is obtained with the calculation of all balance characteristics on a numerical model. The model distribution of heads is used to solve the hydrodynamic problem in the nonstationary formulation. Recommendations for schematization of hydrogeological conditions for the purpose of justification of local hydrogeodynamic models and the study of filtration parameters in the course of experimental filtration work for the calculation of operational reserves were developed. The results of numerical modelling allow evaluating the influence of any potential source of contamination by its geographical coordinates.
