On the issue of corrosion in the operation of oil and gas wells

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