METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2002 - IPC

Abstract RU 2188315 C1

FIELD: oil producing industry; applicable in development of nonuniform water-encroached oil pool. SUBSTANCE: method includes oil withdrawal through producing wells, injection of working agent and polymer dispersed system into injection wells. Polymer dispersed system is formed by successive injection of polymer aqueous solution and aqueous dispersion of solid particles, and salt of carbonic acid. It is injected together with aqueous dispersion of solid particles, or after injection of aqueous dispersion of solid particles in the form of solution or dispersion of salt of carbonic acid in water. Salt of carbonic acid is used in amount of 6-15% of amount of solid particles in dispersion. After that aqueous solution of acid is injected and treated materials are allowed to stand for 0.1-0.5 day for process completion. EFFECT: higher efficiency of oil displacement from low-permeability zones of pool, and higher oil recovery. 2 ex
