METHOD FOR DEVELOPMENT OF OIL DEPOSIT WITH STRATA ZONES WITH INHOMOGENEOUS PERMEABILITY

摘要

FIELD: oil production. SUBSTANCE: method includes placing production and injection wells the bottoms of which form a system of area seven-point member. Portions of displacing agents of PAV solution and polymer solution are injected through injection well. When polymer solution injected through injection well, extraction is boosted in production wells with improved permeability, and extraction is restricted in production wells of lower permeability zone. When PAV solution injected through injection well, extraction is boosted in production wells with poor permeability, and extraction is restricted in production wells of good permeability zone. EFFECT: increased efficiency at the expense of increased influence with PAV solution on stratum zone of poor permeability with bottoms of production wells placed in zone of decreased permeability as compared to permeability of zone with injection well. 1 tbl, 1 dwg
