In this article, a theoretical and experimental study of the processes of embedding the centralizer bars on the walls of the well during drilling is carried out. For this purpose, a mathematical model has been created that describes the dynamics of the process, taking into account the axial load on the bit and the own weight of the drilling column. The formation of a compacted core in front of the centralizer, as well as the stress-strain state of the medium, is considered. The proposed approach allows us to take into account the possibility of introducing a centralizer on the walls of the well and adjust the curvature parameters of the trunk of inclined wells. The results of this study can be useful for optimizing the drilling process and improving the efficiency of wells. The study is aimed at analyzing the technical and economic aspects of the installation of inclined wells, based on the state of spatial curvature of the trunk. It was found that stabilization of the design azimuth of the curvature is a difficult task in deep inclined wells due to the lack of continuous information about the course of the curvature parameters. Technological problems such as measurement inaccuracy and selection of equipment parameters are described. Special attention is paid to the use of a magnetic translator and a downhole inclinometer to accurately orient the deflector at the bottom of the well, which is the most accurate and cost-effective method in modern drilling operations.
