EXPANSION OIL WELL CEMENT BASED ON SUBSTANDARD RAW MATERIALS

Grouting cement is a type of Portland cement designed to insulate pipes of oil and gas wells and protect them from groundwater pressure, shifts of ground layers, and the negative effects of aggressive media. When solidified, the cement mortar forms a monolithic jacket, impermeable to liquids and gases. The material adheres firmly to the metal pipe and to the walls of the trunk drilled in the rock. The use of grouting cement creates conditions for safe operation of wells and prolongs their working period. In traditional construction, this type of Portland cement is not used. The exception is the foundation of drilling piles in difficult geological conditions. That's whay, the article presents the investigation of grouting cement with the basis of substandard raw materials.
