Influence of the Compressive Stress on the Corrosion of Petroleum Casing Premium Connection Material

Article Preview

Abstract:

In order to find the corrosion cause of petroleum casing premium connection material, the fixture was design to simulate material enduring compressive stress, and the fixture was put in high temperature autoclave, and the corrosion rate of two kind casing material(carbon steel and stainless steel) enduring compressive stress were test in H2S and CO2 and Cl- water solution. The result was that compressive stress accelerated the corrosion of petroleum casing steel, and when compressive stress was greater than the value half as the yield strength the corrosion rate increased quickly.
