Abstract

The optimal working time of injection wells is determined by calculations based on a synthetic hydrodynamic model. The formation under study is divided into three zones due to geological conditions: mixed sandstone (ZA), mixed sandstone in the transition zone (ZB), low-permeability reservoir (ZC).
The determination of the working time of injection wells in the zone «ZB» is considered. With the averaged technological parameters of wells and geological conditions, the optimal time for working out injection wells in the «ZB» zone was 4 months with an increase in oil production by element 1154.5 tons, and an increase in net present value of 1.29 % over 20 years. When geological and technological conditions changed, the optimal working time varied from 2 to 8 months. In order to maximize oil production and economic effect, it is necessary to take into account the geological and technological parameters when determining the optimal time for working out injection wells.
Materials and methods. The results of calculations based on a synthetic hydrodynamic model (multivariate modeling). Analysis of the influence of geological and technological parameters on the optimal working time of injection wells.
