Beschreibung
Zusammenfassung:	FIELD: well construction; applicable in production of grouting materials for cementing and casing of oil, gas and other wells. SUBSTANCE: grouting composition includes oil-well portland cement, expanding additive and surfactant. Expanding additive is used in the form of sulfoaluminate-line sinter, and surfacant in the form of sodium abietate, and additionally, heat-treated clay. Grouting composition contains the following ratio of ingredients, wt.%: oil-well portland cement, 49-74.9; sulfoaluminate-lime sinter, 5-20; sodium abietate, 0.1-1.0; heat-treated clay, 20-30. EFFECT: high water tightness of cement stone and adhesion strength of grouting composition. 2 tbl
