ABSTRACT
The article discusses the concept of using modern materials for self-healing of cement stone, which will improve the quality of construction of oil and gas wells, as well as provide a safer work from an environmental point of view.
To date, self-healing of cement stone is represented by three conceptual approaches: self-healing system based on capsules (granules), in the shell of the vessel (fiber) and without shells.
This paper presents the results of experimental studies on the effect of adding rubber particles on the self-healing ability of cement stone. The paper discusses the self-healing of cement stone after creating artificial cracks. The effect of various environments on the kinetics of swelling, as well as the effect of temperature on the self-healing process has been studied. The research results prove the fundamental possibility of the existence of self-healing cements and the possibility of the restoration of cement sheath.
