Failure Analysis on Fracture of a 3-1/2″ P110SS Tubing

Article Preview

Abstract:

The tubing, as a key ingredient in the well development, worked always under very complex stress and corrosion conditions, the failure of the tubing could cause huge losses. In this paper, a fractured 3-1/2″ P110SS tubing was analyzed through physical and chemical properties testing, SEM, EDS, and XRD method. The results showed that the failure of the tubing was belong to hydrogen sulfide stress corrosion cracking. The tubing material could not pass the SSC test, it was inappropriate to use in well contained high hydrogen sulfide.
