FIELD: oil, gas and coke-chemical industry.
SUBSTANCE: invention relates to grouting composition used in oil and gas industry when shutting down formations, isolating water inflows and elimination of lost circulation. Grouting composition for liquidation of absorption zones up to 10 m3/ h contains the following reagents at the following ratio, kg: Polyekosil: 144–146, Bioxane: 0.02, “ПолиТЩР-2”: 2000, Water: 855–854.
EFFECT: improved water-insulating properties of the backfill composition due to improvement of its strength properties and increase of hardening time, recovery of drilling mud circulation.
