Background: Cementing of the production column is an important stage of well completion, which in turn requires the correct selection of the formulation of grouting solutions that ensure the durability of well operation. Aim: In this article, the analysis of the main factors affecting the quality of well cementing at each stage is carried out, and the impact resistance of grouting materials in the bottom-hole zone of the well is considered in detail. Materials and methods: The method of assessing the impact resistance of grouting materials by the magnitude of impact strength is described. Results: The results of research work carried out on the basis of this method with reinforced grouting solutions used to increase the specific impact strength of cement stone are presented. Conclusion: Experimental studies have shown the effectiveness of polypropylene fiber and building micro-reinforcing fibers at concentrations of 0.25 and 0.5%.
