The technique of the criterion selection of the objects of availability for implementation of non-stationary flooding technology is developed and approved in the conditions of Slavneft-Megionneftegaz OAO fields. New chemical reagents compositions for the alignment of the profile of water injection well and stimulation of oil production, including in conditions of highly partitioned low-permeable reservoirs, are developed and tested. The possibility of realization of unsteady flooding and address wells treatments for the alignment of the profile of water injection well in conditions of low-permeable reservoirs is shown.
Key words: nonstationary fooding, enhanced oil recovery, address processing wells
