Key words: reservoir with supercollector, cyclic flooding, asymmetrical cycle, deformation processes, numerical researches.

The article presentsresults of numerical researches of oil recovery processes with cyclic flooding application for reservoirs with supercollectors. Estimation of influence of elastic deformations at net reservoir stress variation is carried out. It’s shown that elastic deformations lead to increasing of formation pressure decrease period duration, resulting in oil recovery increase and water-oil ratio decrease.
