“…[ 5 ] Jones et al [ 6 ] investigated the corrosion mechanism for E‐glass fiber in oxalic acid and other organic acid solutions and found that ion exchange in the organic acid solution was the main corrosion mechanism. Li et al [ 7 ] also found that ion exchange was the mechanism in the corrosion of glass fiber in a CO 2 /H 2 S corrosion environment. Li et al [ 8 ] evaluated the hydrothermal aging mechanism of aramid fiber composites and proposed an aging model.…”

High‐performance fibers such as carbon, aramid, and glass fiber generally have excellent mechanical, thermal, and chemical resistance and they have potential applications in oil and gas exploitation where high‐temperature and high‐pressure (HTHP) H2S/CO2 corrosive environments usually exist. To investigate the corrosion behavior of these fibers under such environments, two corrosion environments (HTHP water, HTHP H2S/CO2) were simulated in a high‐temperature high‐pressure reactor. Scanning electron microscope, X‐ray diffraction, density measurements, and single fiber tensile test were performed to study the surface morphology, crystal structure, and mechanical properties before and after corrosion. After exposure to the second corrosion environment, the carbon aramid fibers had no obvious mass loss and tensile strength retention of 70.28% and 49.66%, respectively. The surface of the aramid fiber and carbon fibers was significantly damaged which led to an increase in surface defects and a decrease in crystallinity. The glass fiber had clear weight loss due to a large number of defects being formed in the structure and the retention of tensile fracture strength was 48.18%. Corrosion under HTHP H2S/CO2 conditions caused more serious damage to the high‐performance fiber structures.

Aramid and poly(p-phenylene benzobisoxazole) (PBO) fibers are two of the most represented organic fibers possessing high strength, high modulus, excellent thermal stability, and chemical resistance, with great potential in oil and gas applications. The reliability of organic fibers for oil and gas applications were systematically evaluated by studying the corrosion behavior and mechanisms in high-temperature and high-pressure (HTHP) hydrogen sulfide (H2S) and carbon dioxide (CO2) corrosive environments. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), elemental analysis, density measurements, and single fiber tensile testing were conducted to study the surface morphology, chemical structure, crystal structure, thermal, and mechanical properties of aramid and PBO fibers, before and after corrosion. After corrosion, the crystallinities of aramid and PBO fibers decreased by 19.4 and 4.4%, respectively, whereas their tensile fracture strengths decreased by 50.34 and 28.18%, respectively. Hence, the corrosion resistance of PBO fiber is better than aramid fiber. The decrease in tensile properties of aramid and PBO fibers can be attributed to the higher internal porosity, more number of surface defects, and lower crystallinity after HTHP H2S/CO2 corrosion. This work provides some fundamental information regarding the selection of high-performance organic fibers for oil and gas applications.
