成果简介	NOVELTY - Invention can be used in cementing casing strings. Self-healing grouting mortar with controlled technological properties contains a mixing liquid—water and a base. Base includes oil well portland cement, polyacrylamide-based filtration reducer, silicone polymer-based antifoaming agent, a plasticising additive based on a polycarboxylate copolymer, an expanding additive and a complex mineral additive. Complex mineral additive includes nano aluminum oxide, ground talc, calcium hydroxide and gypsum hemihydrate. Expanding additive is a product of combined grinding of wastes of blast-furnace slag and quicklime. Content of water in grouting mortar provides water-mixture ratio with base of 0.45–0.70. USE - Well drilling. ADVANTAGE - Improved insulation capacity of cement stone obtained from the proposed grouting mortar. 1 cl, 1 tbl, 5 ex
