Abstract: Explorative experiment of airinjection oxidation is carried out for SZ361 heavy oil through examining the acid value of the oxidated heavy oil and the change of O2 content in produced gas,and the mechanics of airinjection catalytic oxidation oil displacement are further confirmed.The technology is feasible which is confirmed in theory and technology.The results of explorative experiment show that the content(bulk fraction) of O2 in produced gas is 2.5% when heavy oil is oxidated for 5 days,the catalytic oxidation effect for heavy oil is obvious.Under the experimental conditions,50g heavy oil,the volume ratio of catalyst and oil 1.4%,air pressure 0.7MPa,90℃,48h,60% H2O and 300r/min,the viscosity of offshore heavy oil decreases from 2004mPa?s to 100mPa?s,viscosity reduction ratio of it reaches to 95.0%.
