Abstract
The study is devoted to the analysis of the current conditions for cementing of deepwells in Western Kazakhstan and the development of the theoretical foundations for obtaining lightweight corrosion-resistant cementing materials using local raw materials.
 This paper presents the theoretical justification for reducing the density of grouting materials and increasing the corrosion resistance of the resulting grouting mortars and stone with the addition of natural carbonate materials for the presence of acidic aggressive components (hydrogen sulfide and carbon dioxide) in the formation fluids. To obtain a homogeneous dense structure of cement stone, disintegration technology is justified.
 During the research, both standard and special methods were used to study the properties of grouting materials in a corrosive environment. Processing of experimental data and planning of the experiment was carried out using methods of mathematical statistics.
