The problem of leakage production strings in production and injection wells is becoming more and more urgent every year in Russia’s fields. As a result, the water encroachment of produced products increases, and as a result, the operation of wells becomes unprofitable. The main reasons for the leakage of wells are aging of well stock, poor quality cementation during final works during drilling, corrosion processes in places where aquifers come into contact with the string, killing of wells at pressures higher than the pressure of pressing, depressurization in coupling joints, metal corrosion and other technological reasons. Identification of factors affecting the deformation of production strings in the process of well corrosion is necessary and important, as it is taken into account in the development of measures to increase the accident-free operation of wells. 725 wells of PJSC TATNEFT were analyzed in this work. The analysis revealed that one of the reasons for the corrosion of production strings is the presence of lost circulation horizons, which confirms the analysis.
