Abstract: When cementing wells, it becomes necessary to carry out technological measures to improve the methods of regulating the properties of grouting systems that ensure high-quality fastening of wells in difficult conditions. There is a need to develop a technology for obtaining special cement compounds and recommendations for their use in drilling oil and gas wells. The purpose of this article is to substantiate the need for research aimed at improving the quality of fastening oil and gas wells by improving scientifically sound technological solutions for regulating the properties of grouting systems. In this paper, the technological properties of grouting materials and additives designed to increase the quality of well cementing are considered. A review of research has been conducted on ways to regulate the properties of grouting materials for cementing oil and gas wells. It is shown that in order to obtain high-quality grouting solutions used for fixing the casing and taking measures to eliminate inter-column pressure, it is advisable to use special cement mortars and additives based on local raw materials. Such materials can be, for example, individual spent clays, saponified semi-stones, and others. The formulation of grouting solution can be widely used to produce multifunctional grouting solutions in order to improve the quality of well fastening.
