METHOD OF NON-HOMOGENEOUS OIL RESERVOIRS PRODUCTION

摘要

FIELD: oil-and gas industry.;SUBSTANCE: invention related to oil industry, particularly to non-homogeneous water oil reservoirs production methods, can be used for production wells water in-flow limitation. The method includes gradual pumping in of a cross linker bank - calcium chloride or magnesium chloride, an insulating composition edging - polymer water year around PWEA, saturated with a wood powder, cross linker calcium chloride or magnesium chloride banking, pumping in a displacement agent - a mineralised water at the following components ratio wt %: PWEA 5.0-10.0, wood powder 0.5-10.0, calcium chloride or magnesium chloride 5.0-15.0, the rest is water. Invention develops in formula subclaime.;EFFECT: non-homogeneous reservoirs, developing at the late stage, oil recovery rate increase.;2 cl, 2 tbl, 2 ex
