METHOD OF INJECTION WELLS INPUT PROFILE ALIGNMENT AND PRODUCTION WELLS WATER FLOW LIMITATION Russian patent published in 2009 - IPC E21B43/22 C09K8/60 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production, particularly to heterogeneous stratum filtration characteristics change, reservoir recovery increase and decrease in production wells water content with receiving maximal effect at the late stage of oil field development. Method of injection wells input profile alignment and production wells water flow limitation includes pumping working agent into stratum-fresh or mineralized water and insulating media, which consists of wt %: polymer POLYCELL AQUABLOCK 140 0.05-0.08, bonding agent chrome acetate 0.005-0.008, the rest is water, executing 1-4 days process delay, at that insulating media made as a suspension, prepared in a such way that polymer POLYCELL AQUABLOCK 140 and water solution of chrome acetate dispensed into water simultaneously, mixed during 15 minutes and pumped into the well. Invention develops in formula subclaime.

EFFECT: increase of gelling composition insulation parametres and in quality of injection wells input profile adjustment, because of better strength characteristic of media which keeps gel bonding structure and at the same time allows to adjust time of gelling, device arsenal diversification.
