PROCESS OF ACTION ON FIELD WITH INHOMOGENEOUS COLLECTORS Russian patent published in 2002 - IPC

Abstract RU 2184218 C1

FIELD: oil production. SUBSTANCE: process is specifically related to methods increasing recovery of oil in fields with inhomogeneous collectors. Process of action on field with inhomogeneous collectors includes extraction of oil through production well and alternating pumping of alkaline fringes of derivative of cellulose and clayey suspension into pool. Derivative of cellulose is pumped in the form of dispersion in alkaline solution with pH= 8-11 with volumetric proportions between alkaline fringes of clayey suspension and dispersion 1:1.5-2.0. Fringes are pumped either into injection or production or both wells at same time. EFFECT: increased strength properties of grouting sediment and increased oil recovery of field. 1 cl, 1 tbl
