METHOD OF DEVELOPING OIL DEPOSIT Russian patent published in 1999 - IPC

Abstract RU 2136872 C1

FIELD: oil and gas production. SUBSTANCE: when performing late-phase development of oil deposit, oil is extracted through producing wells, working agent is injected through injecting wells, and, periodically, aqueous dispersion is injected through injecting well. Dispersing medium of aqueous dispersion is composed of clay powder and water-soluble polymer powder. Injection of aqueous dispersion is carried out by edges. Passage from one edge to another is accompanied by 1 to 10% increase in injection pressure. In each subsequent edge, amount of amount of clay powder is decreased and that of water-soluble polymer increased. Total decrease in clay powder ranges from 15 to 0 wt %, while water-soluble polymer content increases from 0.001 to 1 wt %. EFFECT: : increased oil recovery of formation. 2 cl
