FIELD: gas and oil production.
SUBSTANCE: quick-setting spacer mix for water and gas flow insulation in low-temperature oil and gas wells, including carbamide-formaldehyde resin, acid solidifier, barite and water, with 2% aqueous solution of nitryltrimethylphosphonic acid as acid solidifier, at the following component ratio, wt %: carbamide-fimraldehyde resin 45.0-50.0, 2% aqueous solution of nitryltrimethylphosphonic acid 2.5-4.5, barite 40.0-49.0, the rest is water. The invention is developed in dependent points of formula.
EFFECT: reduced gas permeability, increased oil recovery from beds, intensified oil production.
