As the infrastructure in the process of oil and gas field production, with the continuous in-depth development of oil and gas fields, the actual production environment of oil and gas wells is becoming worse and worse, and the failure problem of the threaded joint by corrosion is becoming more and more prominent and serious. To ensure the integrity of wellbore and improve the service life of oil well pipe, several types of corrosion of oil well pipe thread joints have been introduced with their corrosion mechanisms and influencing factors also were analyzed and summarized in detail. In this paper, the types of corrosion and the corrosion protection technology are systematically summarized. The development direction of oil well pipe thread joint corrosion is discussed, and it is considered that the research on oil casing corrosion protection under the coupling of multiple factors is the main research direction in the future.
