The application of anti-corrosion materials in the oil and gas field development

摘要

With the development of some severely corrosive oil and gas fields, the phenomenon of material corrosion is increasingly serious. Through a large number of literature investigation, comparing with the advantages and disadvantages of anti-corrosion materials in CO_2, H_2S and Cl~- concomitant environment. In the development of oil and gas filed use some new anti-corrosion materias. CRAs under highly corrosive conditions remains the most effective and relatively economical choice in downhole and wellhead. At special pipe sections usually use super high-density polyethylene and nylon. Process piping usually use CRAs and CLASs. In water treatment systems use non-metallic pipes (HDPE, FRP). Oil and gas output pipelines and rubber seals use CLASs, try to slow down the corrosion.
