GTOUTING MORTAR FOR CEMENTATION OF OIL-AND-GAS WELLS UNDER CONDITIONS OF POTASSIUM-MAGNESIUM AGRESSION

摘要

Grouting mortar for cementation of oil-and-gas wells under conditions of potassium-magnesium aggression includes plugging Portland cement, additive for increase of corrosion stability, nitryltrimetylphosphonic acid and water. In addition solution includes sodium chloride, at that as additive for increase of corrosion stability one uses modified additive to grouting mortars.
