چکیده:

Six corrosion inhibitors have been evaluated for carbon steel in seawater undcr downhole conditions. Thc corrosion rates of carbon steel in the absence and presence of inhibitors have heen determined using the linear polarizarion resistance (LPR), weight loss method and electrochemical impedance spectroscopy (EIS). The corrosion rates of carbon steel that were tletermined by rhe LPR method were conducted for specimens exposed to uninhibilcd and inhibited sseawaler under downhole conditions using a 3 litre volume Hastelloy C-22 autoclave, A corrosion meter was used for corrosion rate dctcrrrmination. the weight moss method was based on the wheel test method, which consisted of a rotating wheel machine with 24 compartments of 200 ml glass bottles. test specimens and varous concenttations of inhibitions were placed in these bottles for 14 days after witch the weight loss was determined. the EIS method was performed to determie the inhibitor that has the abitity to form a protective film pf the surface of the steel. the most effeective corrosion inhibitor found was on amide-based inhibitor at a corcentration of 5 to 10 ppm.
