Hydrodynamic simulation of reservoir fluids filtration at diverter technology conditions
There were base equations of mathematical physics for three-component flow case (oil, water, polymer). It was required to simulate diverter technology application and simulation approach of this technology. Approximate estimation algorithm for high-conductive pore volume was shown. It is based on history production data. Also synthetic hydrodynamic model was built to estimate technological and economic efficiency of address diverter technology application. The results of technological and economic efficiency estimation were presented. There was the reason of quarter pattern failure comparing to entire model cell of flooding. Injectivity profiles for without-diverter technology and application technology cases were shown. It was illustrated as discrete after-application time dependence. These profiles described change of vertical sweep efficiency and they were evidence of injection profile smoothing. Also studies about influence of well shut-in time on oil recovery efficiency were conducted. Based on results of numerical study and theoretical assumptions, it gave the recommendations to increase success of method. This study will be useful for petroleum engineers. It helps them to make a plan of geological and technical actions, effect forecasts and estimation of technological and economic efficiency. Also this study will be useful for simulation engineers to take into account some of moments during the model building, history matching and making forecast variants.
