Galvanic corrosion behavior of dissimilar casing steels in high sulfur-containing gas wells
Source abstract
Abstract
Abstract The galvanic corrosion behavior of C110 carbon steel and 17-4PH stainless steel as casing steel was investigated in a simulated H2S/CO2 annulus environment using a corrosion weight loss method, zero resistance ammeter (ZRA) method and surface analysis technology. The result shows that the driving force of the galvanic corrosion is the potential difference between the coupling metals. Both the vapor and liquid phases can exacerbate galvanic corrosion effects. The corrosion rate of the C110 carbon steel increases with an increasing cathode to anode area ratio. The coupling structure of C110 and 17-4PH should be avoided in a casing string design for use in a high sulfur-containing environment.
