Failure analysis of 3Cr oil pipe body fracture by Jinzhi Wang, Yan Li, Xianren Kuang, Yaqin Ma, Jinheng Luo, Yan Long

“…The natural gas injected by gas lift contains oxygen and trace hydrogen sulfide, and the formation water is calcium chloride water type, which together form a high stress corrosion cracking sensitivity environment. In addition, corrosion pits and stress corrosion cracks are generated in the service process of the oil tube, which makes the bearing capacity of the oil tube decrease, and plastic fracture of the oil tube occurs under large axial load.…”
