Ensuring the tightness of the insulation and durability of the cement stone depends on many factors that occur at all stages of cementing the operational column. If one of them is the penetration of gas during cementing or after the delivery of cement mortar into the annular space, then another factor is in-well work that creates dynamic loads on the cement stone and violates the tightness of the annular space insulation. These factors can be the cause of many problems that arise during the operation of the well. Therefore, improving the quality of well anchoring taking into account these factors, especially in the productive formation zone, is always relevant. Since the initiation of gas penetration into the cement mortar can manifest itself when moving upwards in the annular space and during its hardening, it becomes necessary to use expanding and reinforcing additives in the development of grouting material formulations. The article offers for consideration the results of a study conducted to assess the effect of reinforcement on the properties of grouting materials with expanding additives, as well as the role of other modifying additives. They make it possible to increase the deformation stability, prevent the destruction of cement stone when exposed to shock loads and minimize the processes of gas entering the cement mortar (stone). Instruments and equipment conforming to API and GOST 1581–96 standards were used for the research. The results of experimental studies made it possible to obtain grouting solutions with expanding and reinforcing additives at a concentration of 0.25 %, providing the necessary deformation stability of the grouting stone.
