Experimental and numerical study on internal pressure load capacity and failure mechanism of CO2 corroded tubing

With the purpose of researching on the influence of CO2 injection tubing with corrosion defects to the safety production of CO2-EOR flooding, experimental tests and finite element simulations were conducted to analyze the failure pressure and stress distribution of P110 pipe with single point corrosion, axial line corrosion and uniform corrosion defects. Metallographic examination was also done to investigate the micro-mechanism of pipe failure....
