Grouting mortar |
| abstract |
FIELD: grouting mortars; may be used in drilling oil and gas wells. SUBSTANCE: grouting mortar has oil-well cement and plasticizer in the form of polyelectrolyte complex of resorcinol-formaldehyde oligomers and polyethylene-polyamine stabilized with formaldehyde. Content of plasticizer in mortar amounts to 0.05-0.45%. EFFECT: higher efficiency of plasticization and increased strength of cement stone. 1 tbl |
