摘　　要：The influence of poly（methylmethacrylate-co-N-vinyl-2-pyrrolidone）, P（MMA-co-VP）, on corrosion of carbon steels（J55, N80, P110 SS and C110 steels） in 3.5 wt% NaCl solution saturated with CO2 was evaluated using static high pressure and high temperature（HPHT） autoclave. The surface was further evaluated by X-ray diffraction（XRD）, scanning electron microscopy（SEM） and contact angle measurements. Quantum chemical calculations have been used to evaluate the structural, electronic and reactivity parameters of the inhibitor on the steels surface. SEM, XRD and contact angle measurement studies reveal that the surface of metals are quite unaffected after use of inhibitor in 3.5% NaCl solution saturated with CO2.The influence of poly（methylmethacrylate-co-N-vinyl-2-pyrrolidone）, P（MMA-co-VP）, on corrosion of carbon steels（J55, N80, P110 SS and C110 steels） in 3.5 wt% NaCl solution saturated with CO2 was evaluated using static high pressure and high temperature（HPHT） autoclave.
