L80 3cr oil casing pipe

Development background of non-API 13Cr series martensitic stainless steel oil casing

Research shows that for oil and gas wells containing CO2, 13Cr martensitic stainless steel should be used; for the coexistence of H2S and CO2, super 13Cr martensitic stainless steel, 22Cr-25Cr duplex stainless steel and even nickel-based corrosion resistant alloys must be used to meet the demand . Cr is an effective element to prevent CO2 corrosion. It can quickly form a dense and extremely thin Cr2O3 passivation film on the metal surface. As the Cr content increases, the effect of resistance to CO2 corrosion increases. The CO2 partial pressure is the main factor affecting the corrosion rate. The CO2 corrosion rate increases with the increase of the CO2 partial pressure (Figure 1). In engineering, the CO2 partial pressure of 0.02MPa is generally determined as the critical value for CO2 corrosion. Oil well temperature generally increases with increasing well depth. In most cases, the increase in CO2 partial pressure and temperature increase are synchronized.
