Abstract

At Hassi-Messaoud, the recuperation of oil is assisted by injection of water extracted from Albian aquifer. To increase the injection capacity of the water, API N80 concentric has been installed along production wells, the difference between the temperature of the water wells and that of the water injected into the concentric generates a temperature gradient ΔT varying in depth and up to 16°C. The present study endeavors to examine, first the effect of tempering temperature on the corrosion behavior of API N80 pipe in Albian water at different temperature gradients and then to determine the nature of corrosion deposit. Polarizations results for samples tested at different ∆T shows a general decline in corrosion rate values with increase in tempering temperature. FTIR and XRD analysis revealed that corrosion scale is heterogeneous; the formation of various compounds depends strongly on temperature.
