Title: Corrosion Behavior and Characterization of Typical Well Pipes in CO_2 Flooding Environment
Abstract:Corrosion behaviors of typical well pipes(N80,P110 and 3Cr) in CO2 flooding environment were investigated using high-pressure autoclave.The corrosion rates of well pipes and the inhibition efficiencie...Corrosion behaviors of typical well pipes(N80,P110 and 3Cr) in CO2 flooding environment were investigated using high-pressure autoclave.The corrosion rates of well pipes and the inhibition efficiencies of mannich base were calculated.In addition,surface characteristics and chemical composition of corrosion product films were analyzed.The results indicated that the corrosion rates of the experimental samples increased with increasing CO2 partial pressure,the anti-corrosion ability was in the order of P1103CrN80,the inhibition performance of mannich base was good,and the main corrosion products on sample surfaces were FeCO3 and CaCO3.Read More
