Abstract
In simulation of oilfield environment, according to the corrosion rate, corrosion morphology, corrosion composition and matrix microstructure of domestic 100S casing steel, the H2S/CO2 corrosion behaviors were studied. The results showed that, in the simulation of temperature range, the uniform corrosion rate of 100S casing in 110℃appeared minimum value, but with the temperature rise, the electrochemical corrosion process of the cathode and anode were accelerated and accelerate the dissolution of corrosion product films, the corrosion rate was increased. Under the four different temperature H2S/CO2 corrosion conditions, H2S corrosion played an important role, and did not appear FeCO3,which is the corrosion product of CO2.关键词
