Abstract
Because of its superior strength, low elastic modulus, and exceptional resistance to corrosion, titanium alloy is commonly used as a replacement for carbon steel in the construction of oil well pipes. This paper starts with the application of titanium alloy in oil well pipes in the petroleum industry, summarizes the research progress of its mechanical properties and corrosion properties in titanium alloy drill pipes and oil casing, and compares the fatigue life of several common carbon steel materials and titanium alloy in the petroleum industry. At the same time, the influence of adding metal elements and optimizing the manufacturing process on the corrosion resistance of titanium alloy is discussed. Finally, the problems that titanium alloys may face in the actual production and application process are put forward.
