Investigation of the effectiveness of armored cable in protecting the equipment of electric centrifugal pumps from corrosion

\nThe purpose of this article is to study the effectiveness of armored cable, namely, применthe use of armored four-core cable to protect the installation of an electric centrifugal pump (ESP) from corrosion failure. Method: at the heart of the method, we consider the use of various protections such as: the impact of the inhibitory protection method and the electrochemical (cathodic) protection method, which in turn prevent the oxidative destruction of oilfield equipment parts. Result: an analysis of the application of cathodic corrosion protection using various connection modes of a four-core armored cable was carried out. Conclusion: the inhibitory method of anti-corrosion protection of equipment (ESP) has not proven itself, while the use of an armored four- core cable increased the inter-repair period by 4 times (up to 870 days). No traces of corrosion were found on the surface of the submersible motor and other underground equipment.\n
