Estimation of the influence of fractures spreading zones on wells performance indicators when organizing injection for a Bashkir site conditions of Akansky oil field based on geological-hydrodynamic modeling
The article is devoted to the studies of carbonate cavernous-fractured reservoirs of Akanskoye field of Bashkirsky site with the aim of the field development optimization. A significant reservoir pressure decrease is observed in the site causing low productivity of producing wells. A focal flooding system is implemented in some that is characterized by low efficiency: the traditional approach to a reservoir pressure maintenance system (RPMS) is of little use for these conditions. The task facing the authors was to evaluate the dependence of the wells performance indicators when organizing injection from their interposition with fracturing zones. The researches resulted in determination of the most effective options of carbonate reservoirs development from technological-economic points of view in the specified conditions. When substantiating them, it is necessary to take into account fracturing spreading.
