原始语种摘要: Abstract(#br)In sour environments containing H2S and water, the casing and tubing yield failure criterion is no longer used because environmental fracture is the main failure mode. In this case, a reasonable material selection and design of casing and tubing can reduce or prevent casing and tubing failure accidents. On the basis of meeting the yield criterion, conventional sulfur resistance casing T95 and quasisulfur resistance casing C110 is designed considering the fracture mechanics method. According to environmental fracture toughness K ISSC calculated by NACE method A and/or D, antipressure fracture strength of C110, and T95, casing is predicted by failure assessment diagram under various conditions. Numerical and experimental comparisons show that antipressure...
