Study of the Corrosion and Protection Technology of Oil and Gas Pipeline

In the majority of oil fields in our country,during the process of exploitation,the associated gas of oil wells usually contains CO2,H2S and other corrosive gases with different ingredients.At the same time,because the oil and gas gathering and transportation system cannot be completely sealed, O2 and other corrosive gases in the atmosphere can enter the oil and gas production system,resulting in a wide variety of corrosion concerning the oil and gas production systems.On account of the present corrosion situation about oil and gas pipelines,this paper is intended to give a brief overview of the CO2 corrosion,H2S corrosion,oxygen corrosion mechanism with their influential factors,and on this basis it further introduces a negative pole protection technology,a corrosion resistance materials anti-corrosion technology,an engineering anti-corrosion technology,a chemical anti-corrosion technology,as well as several commonly used anti-corrosion measures adopted at home and abroad.
