FIELD: petroleum and gas extracting industry.
SUBSTANCE: grouting mortar solution contains Portland cement, water and alkylbenzylmethylamine chloride as a plasticizing agent and polyvinylpyrrolidone taken in the following ratio of components, wt.-%: Portland cement, 66; alkylbenzylmethylamine chloride, 0.1-0.3; polyvinylpyrrolidone, 0.2, and water, the balance. Invention provides enhancing capacity of grouting mortar solution in the hole efficient zone based on increasing time for providing the plastic strength, compression and bending strength, adhesion forces, and reducing cost. Invention is designated for carrying out repair-insulating works in petroleum and gaseous holes.
EFFECT: improved and valuable properties of solution.
