description Disintegrator technology was widely used in the construction industry and in the oil and gas industry. In the process of drilling wells, powdery materials are used, the quality of which often determines the results of the well construction as an engineering structure. The application of disintegrator technology in the processing of clay powders which are one of the main components used to produce washing liquids has shown the high efficiency of this technology. One of the main multi-tonnage materials used in the construction of deep wells for oil and gas is Portland cement. However, the specific conditions of the well and work performance technology establish additional requirements for both grouting cement and also mortar and stone which are obtained from this binder. That refers to high water-cement ratios, rigid frames for density, water loss, sedimentation stability of solutions, high strength and low permeability of the stone. High corrosive activity of reservoir fluids and high temperatures, which often exceeds 100–150о C, set increased requirements to corrosion and thermal resistance of hardening products. The use of modifying additives and mechanoactivation of cements and grouting mixtures allows us to effectively solve these problems. The results of the study how mechanochemical activation of siliceous additives effects on the structure of their surfaces are presented and the increase in the rate of interaction of silica with calcium hydroxide, which is necessary for increasing the life of a plugging stone, is experimentally proven. Improved structure of the produced cement stone after the disintegration treatment of cement is shown.
