METHOD OF CONTROLLING OIL DEPOSIT DEVELOPMENT BY WATERFLOODING Russian patent published in 2001 - IPC

Abstract RU 2162143 C1

FIELD: oil and gas producing industry. SUBSTANCE: method includes injection into injection wells of aqueous solution of polymer and water. Polymer is used in the form of latex SKMS-30 ARK with stabilizing additive. Aqueous solution of said polymer is concurrently injected through group of injection wells with cluster pump plant. Water is injected between fringes of polymer aqueous solution. In so doing, fringes of polymer aqueous solution and water are injected without stopping. EFFECT: increased sweep of formation, higher oil recovery, recovered water cutting of well production due to increased residual factor of resistance. 1 tbl, 3 ex
