Rough model of oil reservoir local area hydrodynamics, based on simple geometrics of regular well grid, decreases accuracy of analysis due to equilibrium offset. Computational algorithm of initially dense element grid reduction, considered in the article, corrects this drawback, providing equality of equilibrium states in full-scale and reduced models. Dynamical error of bottom-hole pressure is compensated by implementation of additional radial nearwell zone, taking into consideration fast hydrodynamics of inflow into well.
Keywords: reservoir modeling, model reduction, aggregation, finite elements, permeability.
