FIELD: oil and gas production.
SUBSTANCE: invention provides grouting composition for use, in particular, in drilling of wells and during performing repairing and insulation operations but also in production of concretes and preparation of mortars. Water based grouting composition containing cement (52.46-76.92%) and plasticizer (0.066-0.41% on conversion to sodium adipates constituting plasticizer) is supplemented by 0.05-1% of water-soluble polymer as stabilizer.
EFFECT: improved rheological characteristics of grouting mortars and mechanical properties of stone, enhanced efficiency of performing repairing and insulation operations, improved lining of well and prolonged operating period in corrosive media.
