Abstract:

Under-deposit corrosion (UDC) is a critical challenge in the integrity management of oil and gas production facilities because it is hidden, rapid-evolving and highly destructive. Its formation mechanism involves the interplay of multiple factors, including electrochemical, microbial, and physical barrier effects. In this review, the evolution process, mechanisms, and main influencing factors of under-deposit corrosion were systematically summarized. The synergistic effects of deposit types, electrochemical behavior, microbial activity, and environmental parameters on the corrosion process were analyzed. On this basis, the current status of application and the mechanisms were summarized for commonly used protection technologies such as scale inhibitors and corrosion inhibitors, as well as their applicability and limitations in practical working conditions. Finally, the future research directions for preventing under-deposit corrosion were proposed, aiming to provide theoretical basis and technical support for corrosion control in oil and gas fields.

Key words: oil and gas field development, under-deposit corrosion, formation mechanism, anti-corrosion technology, corrosion inhibitor
