“…Corrosion is a serious problem that significantly impacts industrial development, particularly in the oil and gas industry, where it has caused serious economic losses and potential safety hazards [ 1 , 2 ]. One of the most common types of corrosion is CO 2 corrosion, which forms an acidic medium that corrodes the metal surface, leading to equipment damage and production interruptions [ 3 ]. The production and transportation processes of oil and gas often face severe CO 2 corrosion issues, impeding the industry’s safe and efficient production.…”

Carbon dioxide corrosion presents a significant challenge in the oil and gas field. This study simulates the corrosive environment characteristics of oil and gas fields to investigate the corrosion inhibition properties of three triphenylmethane dyes. The inhibitive performance and mechanisms of these dyes were analyzed through weight loss and electrochemical testing, revealing that crystal violet (CV) exhibited a superior inhibition effectiveness over malachite green (MG) and Fuchsine basic (FB). At a concentration of 150 ppm in a CO2-saturated 5% NaCl solution at 25 °C, CV achieved an impressive maximum inhibition efficiency of 94.89%. With the increase in temperature, the corrosion rate slightly decreased, and the corrosion rate was 92.94% at 60 °C. The investigated CV acted as a mixed-type corrosion inhibitor and its protection obeyed the Langmuir adsorption isotherm. The corrosion morphology was characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and confocal laser scanning microscopy (CLMS). Quantum chemical calculations and molecular dynamics simulations were employed to validate the corrosion inhibition mechanisms, providing guidance for the further application of these dyes in corrosion control.

Organic anticorrosion coatings (OACs) are the most effective, economical, and environmentally friendly protection strategy for metals. However, the traditional OACs usually inevitably suffer mechanical cracks during their service life. If not repaired in time, the resultant cracks in OACs will result in irreparable corrosion of the metal substrate. More detrimentally, these microcracks are not easily detectable at the initial stage. If OACs can autonomously heal their damage at the initial stage, the microcracks will be repaired in time and the metal substrate will be protected well. Thus, giving OACs the self‐healing capability is a promising strategy for metal protection. Herein, an autonomously self‐healing TiO2‐reinforced silicone polyurea (SPU‐g‐TiO2) elastomer was successfully designed as anticorrosion coating for Q235 carbon steel (QCS) protection. The SPU‐g‐TiO2 elastomer matrix exhibited excellent stretchability with a maximum strain of 3826.72% and fast self‐healing ability with an outstanding self‐healing efficiency of 98.69% for 6 h without any external stimulus at room temperature. The QCS coated with SPU‐g‐TiO2 showed excellent damage resistance and good anticorrosive ability, and it can self‐heal the microcracks generated in its coating in time to prevent corrosive media corroding the internal mental substrate. This work has a positive guiding significance for the development of functional OACs to improve their protection for metallic materials.Highlights A bionic smart self‐healing SPU‐g‐TiO2 coating was successfully synthesized. The mechanical and self‐healing properties are balanced using nanoparticles. The coating features excellent self‐healing capability and stretchability. Q235 steel coated with SPU‐g‐TiO2 shows good anticorrosive ability.

“…As proven green and lowly toxic corrosion inhibitors, organic corrosion inhibitors attract much attention and have a sustainable application in the anti-corrosion industry [4,5]. Based on the adsorption theory [6][7][8][9], elements O, N, P and S in most organic corrosion inhibitors can be easily adsorbed on the metallic surface; especially important, the N atom on the imidazoline ring can be combined with the empty d orbit on the iron atom to enhance the adsorption performance of corrosion inhibitor molecules on the steel surface. This is conducive to the formation of a protective film to isolate the corrosive medium and to effectively reduce the corrosion rate; thus, the concentration distribution of corrosion inhibitor in the wellbore is critical to its film-forming quality and anti-corrosion effect.…”

The wellbore downhole strings corrosion has attracted extensive interest as most of the oilfields in China enter the high water-cut period. Injection of corrosion inhibitors, one of the most effective corrosion protection methods, is employed to mitigate the wellbore corrosion. Nevertheless, its wider application suffers from insufficient knowledge regarding the distribution of corrosion inhibitors inside the tubing, particularly with different inhibitor injection cycles. Thus, in this study, the computational fluid dynamics (CFD) method was first attempted to investigate the hydrodynamics in a tubing and the interactions between the corrosion inhibitor and produced fluid with high water-cut. Key factors including the time, wellbore heights, injection rates, oil phase velocities and corrosion inhibitor viscosities were discussed in detail as regards how they affect the corrosion inhibitor distribution inside the tubing. Feasible formulas were established for predicting the volume fraction of the corrosion inhibitor at different wellbore heights, which showed good agreement with the simulation results. It is noted that the determination of the corrosion inhibitor injection rate depends on both the film quality of the corrosion inhibitor and the stability of the annular flow. Based on the interphase diffusion effect, a new method for determining the intermittent injection cycle of corrosion inhibitor was proposed to maintain the integrity of corrosion inhibitor film at the tubing inner wall.
