“…First, the materials used are sensitive to the environment in which they are used; Second, there is a targeted corrosion medium, and there is enough temperature and humidity for electrochemical reaction; Thirdly, a certain amount of tensile stress is required [8]. 13Cr martensitic stainless steel pipes are not suitable for use in the environment with high Clconcentration, especially in the environment with trace H2S, and 13Cr steel pipes have poor hydrogen sulfide stress corrosion cracking resistance [9]. Many studies have shown [10] that stress corrosion of martensitic stainless steel can occur in Cl-containing solution, sea water, salt spray test in wet atmosphere and sulfide solution.…”

The field service conditions of a well’s collapse tubing were investigated, and the physical and chemical properties of metal materials (chemical composition analysis, mechanical property test, metallographic structure analysis of tubing materials), hydrogen sulfide stress corrosion cracking test of tubing materials, and scanning electron microscopy analysis of tubing cracks and fracture surfaces were tested in this paper. The results show that the major cause of tubing collapse is that the tubing material is super 13Cr (S13Cr). When it is used in the environment containing hydrogen sulfide, plenty of longitudinal stress corrosion cracks is generated on the inner wall, which greatly reduces the actual anti extrusion ability of the tubing. During the gas lift of the well in the later stage, the upper part of the oil pipe was blocked and the oil jacket was in series, and the gas lift pressure was transmitted into the oil jacket annulus, so that the pressure difference between the inner and outer parts of the oil pipe exceeded its actual anti extrusion capacity and collapse failure occurred.

“…In a CO 2 -O 2 -Cl − environment, Luo [33] concluded that, after the oxygen in the defect is exhausted, the chloride ions migrate to the inside of the defect, the cathodic process shifts to the outside and the FeCl 2 existing inside the defect becomes hydrolysed. The hydrolysis acidified the solution inside the defect, thus accelerating the corrosion process of metals inside the defect.…”

Multicomponent thermal fluid flooding has become a widely used and very effective heavy-oil recovery technology, but the harsh CO 2 -O 2 -Cl − environment can lead to serious corrosion perforation failure of the pipeline. Therefore, the influence of O 2 content and main controlling factors on corrosion perforation were investigated through a weight-loss experiment, corrosion defect test, characterization and grey correlation method. The results showed that, with the increase in O 2 content, the general corrosion rate and localized corrosion rate increased. The uneven protection performance of the product after the addition of O 2 was found to be the key cause of localized corrosion. In addition, the synergistic effect of O 2 -Cl − promoted the lateral and longitudinal expansion of pits. The results of the grey correlation showed that the temperature (30-120 °C) had a greater impact on localized corrosion compared with the content of O 2 (0-0.045 MPa) and Cl − (0-16,000 mg/L).

“…Ueda et al [2] found that the super 13Cr stainless steel is susceptible to SCC in the completion fluid of CaCl 2 containing CO 2 and H 2 S gas. Mancia and Liu [3,4] found that 13Cr steel has a high sensitivity to stress corrosion when H 2 S exists, and the cracking is inhibited after the injection of CO 2 . Li [5] has studied the early electrochemical corrosion behavior at the crack tip of 316L stainless steel in a sodium chloride solution under different stresses.…”

The slow–strain-rate tensile test was used to study the chloride stress corrosion cracking (SSC) behavior of 316L stainless steel under the simulated condition of a CO2 gas field in the Tarim Basin, and the effects of CO2, Cl− concentration, and temperature on the sensitivity of SCC were discussed. The results show that the increase of CO2 content has no apparent influence on the chloride SCC sensitivity of 316L stainless steel. With the rise in temperature, chloride SCC’s sensitivity increases, and the change in the SCC sensitivity index Iscc is noticeable. When the concentration of Cl− increases, the sensitivity of chloride SCC also increases. The degree of influence of the three factors on the experimental results can be ranked as follows: temperature>Cl− > CO2. In this experiment, when the partial pressure of CO2 is 0.1 MPa, the temperature is 65°C, the concentration of Cl− is 1,20,000 mg/L, and Iscc of 316L tensile samples has a maximum of 26.8%.
