Applications of Nickel-Based Alloy for Oil Country Tubular Goods

摘要

With the development of the petroleum industry, more and more high temperature, high pressure and high corrosion wells have appeared. In order to adapt to the harsh environment of oil fields, nickel-based alloy oil country tubular goods have been developed and applied in the world. Nickel-based alloy oil country tubular goods have excellent high-temperature performance and good corrosion resistance, but their manufacturing and processing are difficult and the cost is high, which restricts their large-scale application and development in the petroleum industry. In this paper, the microstructure and properties of the commonly used nickel-based alloys were analyzed, the corrosion mechanism in the acidic environment and the pipe processing technology was discussed.
