Abstract:

Aimed at the problems of the well corrosion and scaling in oilfield,we undergo the study of the mechanism and
cause of the well pipe string corrosion and scaling. The relationship between the ion content in different type water media and
the corrosion rate in pumping wells is confirmed by the analysis of produced water ion,corrosion and scaling products. The
corrosion rate calculated with the simulation software and of the actual situation of the corrosion and scaling. A method to
quickly and qualitatively estimate the type of the corrosion and scaling in the NaHCO3 type water is proposed,which lays a
foundation for solving the corrosion and scaling problems

Key words: oil well, corrosion, scaling, simulation calculation, statistical analysis
