Hydrodynamic simulation of the current state of liquid filtration under water emulsion impact on оil layer

Abstract

The article, in order to increase the efficiency of field development, it is proposed to apply water-oil emulsion to the formation along with dewatering. In order to evaluate the results of the complex impact on the oil layer, the method based on the mathematical modeling of fluid percolation in the layer by fixing the flow lines was used. By calculating and visualizing the distribution of hydrodynamic indicators of fluid filtration flows in the formation environment, the fast-acting mathematical model allows for a fairly accurate assessment of the current state of the impact process on productive formations. The proposed method for assessing the current state of liquid percolation during the impact of water-oil emulsion on the oil layer with local detailed solution , in the case of uncertainty - when solving the diagnostic problems that arise due to the lack of geophysical and hydrodynamic (physical, mechanical, lithological and other) data of the current indicators characterizing the reservoir system can prevent many difficulties.
