Effect of acidizing solutions on K{sub IEAC} of 13 Cr and 22 Cr stainless steels
- Halliburton Energy Services, Duncan, OK (United States)
Fracture mechanics environment-assisted cracking tests, using precracked TM0177-90 double cantilever beam (DCB) specimens, were performed on 13 Cr (UNS S42000) martensitic stainless steel and 22 Cr (UNS S31803) duplex stainless steel in stimulation acidizing solutions to simulate downhole conditions. The acidizing solutions used were 15% HCl and 12% HCl-3% HF with proprietary inhibitors. The 13 Cr material was quenched and double tempered to meet the mechanical property requirements of API Spec 5CT Grade L-80. The 22 Cr material was grade 130 (130 ksi minimum yield strength) cold reduced tubing. This paper shows that the low strength 13 Cr material is not very susceptible to crack propagation in acidizing solutions. The high strength 22 Cr material, however, did show susceptibility to crack propagation in the same acidizing solutions while no cracking occurred in NACE TM0177-90 sour brine solution.
